IPV4 v/s IPV6

IPV4 ( Internet Protocol Version4 ) is the most widely used Internet Protocol to connect to the Internet.

It uses 32- bits with a total of 2^32 addresses. With the growth of internet, the number of addresses available will eventually run out!

IPV6 being the newest version would increase the pool of addresses along with many other advantages over the previous version:

- Auto-configuration
- No more private address collisions
- Better multicast routing
- Simpler header format
- Simplified, more efficient routing

An IP address is a binary number but can be stored as text for human readers.  For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf
