Survey and Study of Next Future Problems in IPV4 and IPV6 Created By Different Unreliable Network Issues

Networking

This research paper based on the study of IPV4 and IPV6 related next future problems .We’ve been at the time, computers were big, expensive, and rare. IPv4 had provision for 4 billion IP addresses, which seemed like an enormous number compared to the number of computers. Unfortunately, IP addresses are not use consequently. There are gaps in the addressing a company might have an address space of 254 (2^8-2) addresses, and only use 25 of them. The remaining 229 are reserved for future expansion. Those addresses cannot be used by anybody else, because of the way networks route traffic. The Internet Engineering Task Force (IETF) recognized this problem in the early 1990s and came up with two solutions: Classless Internet Domain Router (CIDR) and private IP addresses. Prior to the invention of CIDR, you could get one of three network sizes: 24 bits (16,777,214 addresses), 20 bits (1,048,574 addresses) and 16 bits (65,534 addresses). Once CIDR was invented, it was possible to split networks into sub networks. So, for example, if you needed 5 IP addresses, your ISP would give you a network with a size of 3 bits which would give you 6 IPaddresses. So that would allow your ISP to use addresses more efficiently. So in this solve the above related problem But the problems for your ISP drives them nuts. All of these problems went into the consideration of the next version of the Internet.
