The Private IP Address

without comments

Given that you are knowledgeable about computer systems and also the world wide web, you must have heard about networks and IP addresses.  A computer system network contains several interconnected computer systems which transmits and receives data to and from one another.  A one of a kind group of numbers is utilized to distinguish each computer system in a network.  This is referred to as the Internet Protocol or IP address.  Each and every gadget which is a associated with a network has its own IP address. is a reserved IP address.  Private IP addresses are usually set up for private networks that are not attached to the Internet.  Nearly all home networks are private despite the fact that they usually are connected to the Internet.  They commonly perform by installing a router to function as a gate and also to send data to the applicable computer systems on the home network.  This allows for multiple computer systems to share the same ISP connection.  Possessing identical ISP connection for numerous computer systems is an advantage because it decreases expenditures compared to each and every computer system possessing its private ISP connection.  The only limitation is that computer systems is a, lets say home network is not readily reachable via the net.

Router manufacturers generally use a default address for the routers.  This unique address is   SMC and Belkin wired and cordless routers are the major users of this address, nevertheless there are various other makers that implement it as their standard gateway. is viewed as the most appropriate for the purpose of configuring routers.  This is for the most part credited to its vast appliance in standard and in many cases operational networking.  It is a reserved IPv4 address, which indicate that a person cannot get connected to any router from outside the home network by using this address.  The router’s public IP address should be used in such an instance.  Non-public IP addresses can be utilized a lot of occasions once they can be found on separate networks; they cannot be within the same network.

Each and every computer on a local network could very well be configured to work with as the default address, however it is better to work with just one system on the network for preventing clashes.  The computer systems which are attached to the router are set to work with this address as the default gateway.   The website in addition features information on how to set up a router.  The specifics for configuring the router may be accessed simply by inputting in any Internet browser. There one may even discover more details regarding how to configure features of routers for example Firewall settings, Wi-Fi Protected Access (WPA), Wired Equivalent Privacy (WEP) and much more.

Anytime a number of computers are attached to the same network, they each are assigned their unique address by the router’s Dynamic Host Configuration Protocol (DHCP).  It allocates numbers in between and so as to steer clear of any clash of IP addresses.   It is essential to be certain that just one computer system within the network employs the standard IP.  As already stated, if this is not ensured, then you are likely to have a clash of IP addresses.

Understanding And Using 19216801

without comments

19216801 is an IP address that is used by most network device manufacturers to set as default Internet Protocol address for home broadband users. The easiest way of setting up the router is to turn on the router and the computer and to connect it to the computer’s network. If one does not have the required network, the router is directly connected to the computer through the provided cables. Next, the browser needs to be opened and this string of numbers (19216801) is used to launch the router’s home page.

As in everything else, to set up a router, one requires a user name and a password to identify the user. For appropriate configuration and for the sake of convenience, every manufacturer provides a unique name and password to access the setup. As per the requirement on a regular basis, one may or may not change the user name or passowrd. The router setup does not come under the category of everyday computer activity. However, if one does change the password, it is advisable to write down the password somewhere secure for the purpose of safekeeping. If all the resorts to regain the lost password fails, the last resort is to reset the router. A button is usually, located, at the back of the router, specifically for this purpose. By applying pressure on it for a recommended amount of time, it helps to reset all the settings, including the password.

Just knowing about IP addresses and setting up a router is not sufficient to learn about computer networking. There are many other aspects that one needs to know about too, to understand the concept. These IP addresses are divided into numerous categories. The previous version was Ipv3, but now the latest one is IPv4 and Ipv5 are still in the pipeline. These IP addresses are classified as private network. A private network is implies that it belongs to a private company.

There are certain terms one needs to familiarize himself such as High Speed Router, Gateway, Caveat and so on. The terms are explained as below:

1)High Speed Router-DSL routers are frequently exploited by the PC networks. More specifically, the PCs running a LAN have a control over this. These routers are used by home users too. They help to set up fast, effective, online connections. The components are also used in online multiplayer gaming too, apart from setting up a network.

2)Gateway- The IP address, 19216801, also functions as gateways. These usually allow a subnet to send data to any other subnet. Gatewaty is where the data is processed.

Other Functions:

The address does not assist in the information travel. It also helps in streamlining network and setting up procedures. It nullifies the need to attach or introduce switches of Dynamic Host Configuration Protocol. Though at times, it is usually the default page, it may be modified as per needs of the router. In the case of networks, the capacity is meant for computer administrators. These features make the aforementioned address so popular for connecting PC s throughout numerous LANs.

Purpose Of IP

without comments

There are two types of network in the cyber world-private and public. is an IP address which can also be written as 19216821 which is the same as so many others. One thing that sets this address apart from the others is it can be used only as a private network. Public network is one where small networks can communicate with one another via the world wide web. And a private network is mainly comprised of small devices within a particular network. In simpler words, it is a broadband which is used for residential or home purposes has this IP address as its factory default.

As mentioned before, there are two kinds of networks private and public. Similarly there are private and public Ip addresses too. To draw parallels between the real world and the virtual world, the IP addresses can be compared to phone numbers. The public phone numbers (public IP addresses) are listed in a directory whereas the private phone numbers (private IP addresses) are hidden.

The IP address is a Class C private IPv4 network address for access points, routers and other network devices put together by the brands SMC, Belkin and other manufacturers. The advantage of this address is any brand, any network or any computer’s settings can be customized to this address. The reason, this address is so popular is because it can be used to change usernames and passwords which is benefecial for the security of the computer as whole.

IP addresses can be used over and over again which may cause problems within a network. For instance, the same address can be used on more than one address and it will lead to IP address conflict and will lead to interference in the working of the Internet. There is an Internet Assigned Numbers Authority which assigns IP addresses to different networks. There are three major blocks of IP addresses for private networks: (10/8 prefix) (192.168/16 prefix) (172.16/ 12 prefix)

Routers are important in setting up broadband connections. But they are also used in operational networking and strategic games which involve many players. The exception is the IP address since it is considered the most widely used and single IP address. Its use is not just restricted to regular networks but also in broadband routers.

Mostly a residential or a private network requires two IP addresses- one for internal network (home) known as LAN and the other for external (internet) connection known as WAN. Finding the IP address is not too difficult. It is also very useful when one needs to fix the configuration or to fix the troubleshooting. For instance, some routers use while others use

The deal breaker with this IP address is it is better if left alone in the smooth functioning in the Internet. Inexperienced users should not try medddling with it. If there is any malfunctioning, it is advisable to send the computer to a dealer or an Internet Service Provider (ISP).

The Binary Subnet Mask

without comments

A subnet mask is a pattern of bits that is usually used to isolate specific portions of a particular Internet Protocol address. When the mask is applied to an IP address, the network interface’s network routing prefix and host address are produced. The routing prefix is known by names such as subnetwork or subnet. The masks are used by network hardware and software to manage and isolate a certain part of the network.

A routing prefix is generally expressed in Classless Inter-Domain Routing (CIDR) notation. This includes following the notations with a slash and the number of the significant parts in the prefix. When a subnet mask is logically calculated with a network interface’s IP address, the result is usually the starting portion of the subnet’s address, that particular interface is belonging to. The remaining part of the IP network address is the interface’s identifier of the host. An Internet Protocol version 4 or IPv4 mask is usually expressed by four octets in dotted decimal form.

The mask is, represented in dotted decimal notation, which is similar to the IP. The commonly used binary code is the one which uses the dual representation of 11111111 11111111 11111111 0000. Another commonly used presentation is This can be used to determine the address of the user’s IP. There are different ways of calculating subnet mask, some of which are listed as follows:

1)The network class (A,B,C) needs to be determined based on IP address:
– If the address begin with 1 to 126, it is Class A
– If the address begin with 128 to 191, it is Class B
– If the address begins with 192 to 223 it is Class C

2)The number of bits need to be determined to define subnets:
– Number of subnets = (2^Number of bits)-2
– Number of bits= Log2 (Number of subnets +2)
For instance- Number of bits = Log2 (6+2)= Log2(8)=3. The three bits in the IP subnet is used as a subnet portion

3)The mask is composed of subnet mask in binary form by extending the default subnet mask with subnet bits. The default set subnet mask for classes A to C are:
11111111.00000000.00000000.00000000 (Class A, network part 8)
11111111.11111111.00000000.00000000  (Class B, network part 16)
11111111.11111111.11111111.00000000   (Class C, network part 24)

4)The binary subnet mask is converted to the decimal-dot form. The binary form contains four octets (8 bits in each). Use the following rules:
For “1111111” octet, write “255”
For “00000000” octet write “0”
If the octet contains both “1” and “0” the following formula needs to be used:
Integer number= (128 x n) + (64 x n) + (32 x n) + (16 x n) + (8 x n) + (4 x n) + (2 x n) + (1 x n)
(where can either be “1” or “0”)

There are various purpose of this feature. It is an important part of subnetting. A user’s PC may be unable to access the network and host portions without it. It also helps to recognize the protocol ID. It helps in functions like decreasing traffic to a particular website, and identify terminals that require to be connected. For the subnet to work, it is essential to establish network connection. This helps the device to know, if the subnet is connected to the Internet. The default route or the address is found by the equipment, with the help of the local subnet or remote network.

What is

without comments

It is common knowledge that an IP address is an important series of numbers assigned to a device to help in the identification of the computer in the network. The number also comes in handy for servers to know which computer is making what request. These days, the addresses are stored under the IPv4, earlier addresses were stored under Ipv3. The IP seies of IPv5 and Ipv6 are being worked upon. Just like 192.168.1 and, the IP address is a private address, meaning it is generally used by private network such as residential addresses.

There are two kinds of networks- the public network which allows the big and the small networks to interact through websites, e-mails and forms of e-commerce and so on. The private network allows the interactions between the devices of that particular network. The large network is usually present in organizations and institutions of academy. The private networks are common amongst residential purposes or small businesses. The IP address can be given to any device or a computer, but has one special quality that sets it apart: it is used for residential broadband routers. The uiqueness of this IP address is, it is usually used by many home networks.

The IP address is in the range of private 1Pv4 addresses with the first two octets as 192.168. Any brand of network router or any computer on a local network can be used to set to use Some routers such as Belkin and SMC may have this particular address as their typical IP address. The purpose of  this IP address may be to change username and passwords. One can just go to the home page and enter the password. After entering the old password and username, they can be reset accordingly.

It is possible to set any network to the IP address. However, to avoid, cyber-legal mashes, it is better to change one’s default IP ( to a customized IP. It is also very easy to change through the network’s router admin console. IP addresses can be used over and over again, but the usability must be excercised by caution. They can be used on different networks. If, they exist on the same network, they can slow down the working of the Internet. In some rare cases, the default IP address may be used in large organizations.

At times, one must maintain two IP addresses at a minimum. There are number of reasons for this. Firstly, the private network needs to be separated from the public network for security purposes. This also helps to keep computers within a network, safe from crackers and hackers. It is also getting more and more difficult to assign unique IP addresses. So, in case eah device is assigned a public IP, the availability of addresses run out.

Knowing about the IP address, will aid the user to solve any issue with troubleshooting that may occur with networks and connections.

Basic IP Address

without comments

Most people do not understand what comprises an IP address. To them, it is mostly a bunch of numericals that are separated by full stops. Although the meaning is not clear in tself, but the purpose of an IP address is easily grasped. Plainly put, the IP address is a sort of an identifying device amongst millions of Internet users. It is important to have an IP address, to determine the location of the device and also to ensure no two devices have the same address. To solve these problems, computer engineers came up with a solution. The strung four segments of numbers  together and named it as IPv4. The series is one such IP address or IPv4, used to identify devices.

There are usually three sets of private IP address, one of which is, used by network devices namely routers as their default IP address. One common problem that arises from use (or rather overuse) of this IP address is, there may be multiple users using the same IP address. It is recommended to change the default IP address, to a personalized address, before adding it to the network. The user guide that is provided with the device will help one set up a new private IP.

The IP is the default Internet Protocol for most residential broadband routers. The address was initially used by Linksys and from then onwards, it has been adopted by devices used  for residential networks such as Westell, netgear and so on.

In today’s world everything comes with a red tape. The scenario is not all that different in the cyber world too. To regulate the use of the same IP address over and over again, there is a body called Request for Comment. The RFC has defined is that particular address that can be marked as a private address which people can use to access the Internet. There are other addresses too within the range of to and To make the identification more convenient, RFC has aligned them as follows: to as 24 bit-block, to as 20-bit block, and 192. 168.255.255 as 16 bit-block.

For those, who cannot establish the network connections, with the address of, there are plenty of options. Aside from this particular IP address, private users can also make a choice between the IP address such as and Establishing one’s personal IP address is an easy task if one has the basic knowledge in setting legal Internet Protocols . This address is also used as a default in case of D-Link router meant for its webpage access. From this window one can access the modem’s settings by default and adjust address filtering, MAC, LAN, WEP and network settings and so on.

To access the IP, one needs to type on the browser’s address bar. Then hit Enter, and click the ‘Go’ link. Here, in this window, one can make changes according one’s needs and requirements. This enables one to configure the device to be used for establishing networks.
