INTRODUCTION
With the internet penetration rate increasing, its vital to know the importance of ipv4 and ipv6. we are focusing on the impact of the exhaustion of ipv4, and what would happen if it really happens, and what are the future options.
What is IP and TCP ?
IP - Internet Protocol
the method by which information is sent between any two Internet computers on the Internet
TCP – Transmission Control Protocol
an important network protocol. TCP allows two hosts to connect and exchange data, and ensures that “data packets” are delivered exactly as sent
Data packets – packets are quantified small about of data, which are transmitted over the network
IP-V4 Exhaustion
IPv4 address exhaustion is the depletion of the pool of unallocated Internet Protocol Version 4 (IPv4) addresses.
The Internet Assigned Numbers Authority (IANA) manages the IP address space globally.
five regional Internet registries (RIR) are responsible in their designated territories for assignment to end users and local Internet registries, such as Internet service providers.
IANA exhausted on January 31, 2011 and the RIR APNIC's exhausted on April 15, 2011
With this some parts of the world have already exhausted their IPv4 allocations, and the remaining RIRs are expected to deplete their pools within a few years.
