The Internet is a beautiful thing that has made our lives simple like never before! In the world of technology and gadgets, there are certain terminologies that a common person remains unaware of while using the web. One such important term is Internet Protocol or an IP Address. Some routers like D-Link or Net gear come with a default IP that is set for many home based broadband networks and is designated as 192.168.o.1.
Getting familiar with “Public and Private” IP Addresses
Your computer has a public IP address assigned to you by your ISP, which must be unique across the entire internet.
The IP address is supposed to be different and unique as it is something which is designated to be used by your devices connected to your home broadband network. Not permissible to be accessed directly, the IP 192.168.0.1 remains inaccessible outside your private network.
There is an organization named as IANA-Internet Assigned Numbers Authority responsible for managing these IP addresses globally. The very first IP address version defined by IANA was called as IP version 4 that contained a 32-bit address consisting of four numbers separated from each other by dots. Each decimal point represents a value lying between 0 and 255, letting IPv4 system accommodate more than 4 billion addresses!
Private IP Addresses
Among these 4 billion unique addresses, there are certain blocks that remain reserved to be in use for private networks called as private IP addresses. This is perhaps the reason why your router does not need to have a private IP address. Rather, it assigns one to each and every device connected to your home, office or enterprise network allowing any device to connect to any other device over that network via the assigned private IP address.
However, private IP’s cannot connect to the internet directly. They need an ISP allowing them to connect to a network first and then connecting to the world of web. These Internet service providers could be many like Time Warner Cable, Comcast, and AT & T etc.
Steps involved in a successful web connection initiates by establishing a connection with the router like the Net gear or D-Link having a default IP address of 192.168.0.1 post which the network connects to the ISP. The ISP then lets us connect to the web and our message gets routed to the recipient.
Public IP address and the IPCv6 standard
Since public IP addresses were supposed to be unique and the initial IPv4 version could accommodate only four billion addresses, the IANA had to come up with something new leading to the development of IPv6 address based on the hexadecimal system.
Finding your Router’s IP address
Simply, open up a web browser from a computer connected to your router’s network and type http://routerlogin.net at the address bar. You will be navigated to a login window. Type in your username and password keeping in mind they are case sensitive. You will come across the Basic Homepage; select advanced and read your IP address under the router’s information.
