Evan Golden 2 / 12 / 01 CIT/TCT 120 Ipv 4 vs. Ipv 6 Ipv 4 is short Internet Protocol Version 4, the same goes for Ipv 6. Most of todays internet uses Ipv 4 witch is almost 20 years old. There has been one major problem with Ipv 4, it is running out of IP addresses (IP addresses are a unique identified for a computer on the internet). Ipv 6 fixes this problem along with many other more insignificant problems.
Ipv 6 also adds many improvements to Ipv 4 in ares such as routing and network autoconfiguration. Ipv 6 is supposed to replace Ipv 4 in a gradually time frame, with the two coexisting for many years. A Ipv 4 address looks like this 10. 1. 1. 1 and a Ipv 6 address looks like this FEDC: BA 98: 7654: 3210: FEDC: BA 98: 7654: 3210. Ipv 6 supports addresses which are four times the number of bits as Ipv 4 addresses (128 vs. 32). This is 4 Billion times 4 Billion times 4 Billion (2 ^^ 96) times the size of the Ipv 4 address space (2 ^^ 32). This works out to be: 340, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 45 6 This is an extremely large address space.
In a theoretical sense this is approximately 665, 570, 793, 348, 866, 943, 898, 599 addresses per square meter of the surface of the planet Earth (assuming the earth surface is 511, 263, 971, 197, 990 square meters). Security more to Ipv 6 s superiority. Encrypting along with authentication are excelent features of Ipv 6 that Ipv 4 couldnt offer, and offers security headers. IPv 6 also allows a sender and a receiver to establish a high-quality, high-bandwith secure path between each other.
