Hey guys,
I will explain How to compare IPV4 to IPV6.
IPV4:-
32 bit long (4 bytes). The address is composed of a network and a host portion. which depends on the address class. address class is defined as A, B,C, D or E depending on the initial few bits. The total number of IPV4 addresses is 4294 967 296.
IPV6:-
128 bit long (16 bytes). basis architecture is 64 bits for the network number or 64 bits for the host number. often the host portion of an IPV6 address (or part of it) will be a MAC address or other interface identifier.
