problem of IPv4 Address exhaustion

1) There are 5 Regional Internet Registries (RIR) whose role is to allocate IP addresses to users . All of the RIRs have entered a stage of “IPv4 exhaustion”, which means that their supply of IPv4 addresses is now limited .Impact of “IPv4 exhaustion” is that a network operator can no longer receive large IPv4 blocks from an RIR which are sufficient to address any significant Internet infrastructure

2)As a customer of an ISP, you may receive one or more addresses which are assigned to you . But ISPs themselves have a shortage of available addresses, it is generally harder to obtain an assignment of public IPv4 in this manner.

3) Since the advent of IPv4 exhaustion in each of the RIR regions, most have adopted rules (policies) allowing IPv4 address blocks to be transferred between consenting parties, under specific conditions.

solutions

By the end of 2012, there will be no more public IPv4 addresses left to allocate to Internet Service Providers (ISPs). The principal solution for the shortage of IPv4 addresses is IPv6, which provides a much larger address space using 128 bits instead of 32 bits. or one can use private addresses for almost everything

Use C programming language. - Remove any newline \n from input string - The input prompt should say "Enter IP Address of your choosing: " - If IP address is invalid, it should print "You entered invalid IP\n" - If IP address is valid, it should print "You entered valid...
