When you connect to the internet, whether you’re using your laptop, smartphone, or tablet, you have an IP address assigned to you by your Internet Service Provider (ISP). It is similar to a mailing address, which identifies where postal mail comes from and where it should be delivered. IP addresses uniquely identify the source and destination of data transmitted with the Internet Protocol.
What is an IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.
The concept of an Internet Protocol address was first introduced in 1973 with the release of RFC 675, Specification of Internet Transmission Control Program, by Vint Cerf and Bob Kahn.

How to hide my IP address?
- A VPN encrypts your internet traffic and routes it through a server in other location, making it appear as if your traffic is coming from the server instead of your computer.
- A proxy server acts as an intermediary between your computer and the internet, forwarding requests from your computer to the website you’re trying to access.
IPv4 vs. IPv6 addresses
|Address style||IPv4 addresses are numeric and have their binary bits separated by dots (.)||IPv6 addresses are alphanumeric and separated by columns (:)|
|Sets of numbers||IPv4 addresses consist of four sets of numbers ranging from 0-255 separated by periods.||IPv6 addresses contain 16 sets of hexadecimal numbers ranging from 0-9 and letters A-F separated by colons.|
|Checksum||IPv4 has checksum fields||IPv6 offers none|
|Mobile compatibility||IPv4’s use of the dot-decimal notation makes it less suitable for mobile networks.||IPv6’s representation in hexadecimal, colon-separated notation makes it more suitable for mobile networks.|
|For example||IPv4: 192.0.2.146 is a valid IPv4 address.||IPv6: 2001:0000:3238:DFE1:0063:0000:0000:FEFB|
