An IP (Internet Protocol) address is a unique identifying number such as 192.43.32.01 assigned to every device connected to the internet to communicate, IP addresses serve several functions, and the two main functions are, they are used for network interface identification and location addressing.
Every time you go online, whether you're scrolling through social media, checking your emails, or streaming a show, your device uses an IP address. IP addresses are like your device's home address on the internet. They help data know where to go just like how mails finds your house.
There are two versions of IP (Internet Protocol) addresses used on the internet, IPv4 and IPv6
IPv4 is the original version that was first deployed in 1983
IPv4 use a four numbers format separated by dots (e.g: 192.16.41.30)
They have a bit size of 32 bit address
The total IPv4 addresses available is about 4.3 billion
IPv4 addresses are the most widely used version today and due to the limited number of IPv4 addresses is what led to the creation of IPv6
By the early 1990s, the rapid exhaustion of IPv4 address space available for assignment to end users and ISPs prompted the IETF(Internet Engineering Task Force) to explore new technologies, and the result was a redesign of the Internet Protocol which eventually became known as IPv6 in 1995
IPv6 uses a format of eight groups of four hexadecimal digits separated by colons (e.g: 2001:0db8:85a3:0000:0000:8a2e:0370:7334)
IPv6 bit size is 128 bit address and the total available addresses is about 340 undecillion (virtually unlimited)
The IPv6 were designed to replace IPv4 and support the growing number of internet connected devices
Advantages of IPv6: Larger address space, improved routing and security features
Your IP address privacy matters because it reveals your approximate location, Shows your internet service provider (ISP), Can be used to track your online activity and hackers can also use your IP address to hack into your device.
