NAT

On April 15, 2011, APNIC ran out of IPv4 addresses to distribute. APNIC was the first regional , Internet Registry to run out of IPv4 addresses. Though this occurred in 2011, industry , professionals predicted this to occur especially with the exponential growth of the internet. In , response to that growing fear of lack of IPv4 addresses for internet devices the industry , developed version 6 of the Internet Protocol (IPv6) and also developed private addresses for a , way for devices that are not IPv6 compatible to still communicate through and to the internet. , Network Address Translation is the primary method of translating one type of address to , another. NAT64 facilitates communication between IPv6 and IPv4 networks. NAT is also used to , convert private addresses to global addresses. There are 3 main forms of NAT used: Static, , Dynamic, and PAT. Static NAT statically pairs up a local IP address to a global IP address. , Dynamic NAT dynamically pairs a local IP to a global IP through the use of a server providing , automatic pairing. And PAT, the most commonly used, pairs multiple local IP to a global IP with , the use of ports. PAT has many benefits especially allowing multiple devices to work under one , public IP address. Overall, NAT has many uses from IPv6 to IPv4 translation as well as public to , private address translation. , , , , ,
