What is IPv6

IPv6 is the new version of protocol designed to solve the problems of IPv4. The main problem with IPv4 was the address space was exhausted due to a 12 digit structure it was capped off at around 4.3 billion (4,294,967,296) addresses. This produced a problem with more people using the internet these days and an increase in PDA's and other wireless devices. IPv6 is the solution to the ever expanding internet and the address exhaustion of IPv4. IPv6 has a much larger address space than IPv4 approximately 340 undecillion that consists of a 128 bit structure. Another big advantage is of IPv6 is it can support a much larger network and eliminate the need of NAT which causes several problems in itself.

An example of an IPv6 address: 6783:3hte:0000:3:cfr8:204:ff8c:9735
An example of an IPv4 address: 64.143.0.123

• IPv6 is 8 octets in hexadecimal format separated by colons as opposed to IPv4's 32-bit decimal format 
• Any four digit group of zeros in an octet can be reduced to one zero or eliminated all-together. We will use our IP address above as an example.

6783:3hte:0000:3:cfr8:204:ff8c:9735 turns into
6783:3hte:0:3:cfr8:204:ff8c:9735 or
6783:3hte::3:cfr8:204:ff8c:9735
