The size of an IP address in IPv6 is _________(a) 4 bytes(b) 128 bits(c) 8 bytes(d) 100 bitsI got this question in examination.My enquiry is from IPv6 in division TCP/IP Protocol Suite of Computer Network

Answer»

The correct choice is (B) 128 bits

For explanation: An IPv6 address is 128 bits long. Therefore, 2128 i.e. 340 undecillion addresses are possible in IPv6. IPv4 has only 4 billion possible addresses and IPv6 would be a BRILLIANT alternative in CASE IPv4 runs out of possible new addresses.
