Essay on Ipv4 vs Ipv6
Intro to Linux Networking
As some may already know every device that connects to the internet has a IP address. Most people don’t know where the IP address came from though. When the internet was created one would assume that IP address soon followed, however that is not the case. IP didn’t exist for a few years after the internet was unleashed on th the world. The original functions of IPv4 addresses were a part of the Transmission Control Protocol (TCP). As a formal protocol, IP was “born” when an early version of TCP developed in the 1970’s. This happened when predecessors of the internet were split into four layers, IP being the third layer.
The key milestone in the development of the Internet …show more content…
To this very day IPv6 infrastructure is being developed and installed throughout the internet backbone and major wide-area networks. Tier-1 internet backbones have already and deployed IPv6 addresses.
Let’s compare IPv4 to IPv6 shall we? IPv4 | IPv6 | Addresses use 32 bits | Addresses use 128 bits | Has a short lifetime | Has two lifetimes; preferred and valid | Uses an Address Mask | Does not use an Address Mask | Address Resolution uses the MAC Address | Address Resolution occurs in its’ self | Variable header length between 20-60 bytes | Fixed 40 header length | Uses a Basic TCP/IP tool to test ping | SAME |
Now that we have covered we can clearly see that, even though IPv4 is amazing and has done its job well, IPv4 no longer meets the requirements this world and internet is demanding of it. It will
