Q: What is IP protocol?
A: The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.
Q: What is main function of IP protocol?
IP, as the primary protocol in the Internet layer of the Internet protocol suite, has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. An Ip adress is assigned for each device within Internet such as 184.108.40.206.
Q: What is IPv6?
A: IPv6 is the sixth revision to the Internet Protocol and the successor to IPv4. It utilizes 128-bit addresses. I’ll explain why this is important in a moment.
Q: Why are we running out of IPv4 addresses?
A: IPv4 uses 32 bits for its Internet addresses. That means it can support 2^32 IP addresses in total — around 4.29 billion.
Q: How does IPv6 solve this problem?
A: As previously stated, IPv6 utilizes 128-bit Internet addresses. Therefore, it can support 2^128 Internet addresses — 340,282,366,920,938,000,000,000,000,000,000,000,000 of them to be exact.
Q: When will be the switch completed from IPv4 to IPv6?
A: The depletion of IPv4 addresses was predicted years ago, so the switch has been in progress for the last decade. However, IPv4 stacks will probably never be switched off completely.
