Private IP addresses form an integral part of the knowledge base developed in networking training courses. With the advent of the knowledge revolution, the importance of private networks has always been on the upward climb. In the business world, time is money and timely information is time saved, and hence money saved. As a consequence, private networks have become an integral part of the information sharing methods of corporate offices. Also, networking is the solution to several resource crunch situations. For instance, more than a dozen computers in a computer lab at an educational institute can share the services of a single printer, all courtesy the powers of networking. Private networks depend a lot on the use of private IPs, and 192.168.100.1 is a private IP.

Private IPs have had a little history associated with them. The idea of private IP addresses like 192.168.100.1 did not initially strike those associated with the early roots of Internet and networking. The focus used to be on giving unique IP addresses to all manufactured networking components as the envisioned purpose was to meet the needs of global connectivity. However, it was soon realized that not all computers were intended to be a part of the global web of Internet. Hence, private IPs were used with an aim to make better use of the limited range of IPv4 addresses. Hence, a range of IPs was explicitly restricted for use as private addresses. The range was decided by IANA and accommodated as many as 65536 addresses between 192.168.0.0 and 192.168.255.255. Obviously, 192.168.100.1 falls in this range and hence qualifies as a private IP address.

IP addresses like 192.168.100.1 and other private IPs have some unique features which separate them from the other IPs. Being private, they are used in networks that are not set with the intentions of encompassing the whole of the world. This means that there can be hundreds and thousands of networking devices that use the same value of the IP address. This can certainly not be the case for even a couple of computers belonging to the biggest network called Internet. With same names, they would lose the uniqueness of identity and would hence cause network clashes. Private IPs, on the other hand, do not suffer from such problems as the recurring use of the same value of the IP address is distributed over an equal number of devices, each being a part of a separate and independent network. Also, their distinctive feature means that IP addresses like 192.168.100.1 do not need to be co-ordinated with any IP registry. Consequently, 192.168.100.1 is used as the default IP address with the devices of a considerable number of networking equipment manufacturers. Apart from the above mentioned range of IPs, the ones falling between 10.0.0.0 and 10.255.255.255, and 172.16.0.0 and 172.31.255.255 also qualify as private IPs.

Routers from a host of manufacturers come with 192.168.100.1 as the default IP. Among these feature Arris, Cisco and Motorola. Arris TM502G router and Cisco 815 router use 192.168.100.1 as the default IP. ‘Default’ here means that when these devices get made in the factories, they are assigned the IP address of 192.168.100.1. When you bring such a router home or to the office, you use the default IP in the form of a web address in the address bar of your browser and access its administrative console. Before that, you will need to connect the router to a PC through Ethernet. Once you hit the Enter key after doing the above mentioned, you are prompted for login credentials. Routers come with their default login details. For instance, the devices manufactured by Ambit, and using 192.168.100.1 as the default IP address have a default username of admin and a default password of ‘password’. Likewise, there are different login credentials for different devices using 192.168.100.1 as their default IP. One can easily find these default login credentials by checking on the World Wide Web or contacting the customer service departments of the manufacturer. The fact that 192.168.100.1 is only used in private networks does not mean that the computer terminals of such a network can’t connect to the Internet. A Network Address Translation procedure enables the connection of private networks with the global Internet.

Network administrators and engineers have the liberty of assigning 192.168.100.1 as the IP address to any router in a home network, even if it is not the default set IP. Conversely, a router coming with 192.168.100.1 as the default IP can get a different IP as well, and this is done through the set up page of the router. The manufacturers that include 192.168.100.1 as the default IP in their equipments are counted among the more prominent faces in the networking equipment market, and hence, it is essential for upcoming and practicing networking engineers to learn the tricks of the trade as far as 192.168.100.1 is concerned.
