KEY DIFFERENCE IPv4 is 32-Bit IP address whereas IPv6 is a 128-Bit IP address. ... IPv4 supports broadcast whereas IPv6 doesn't support broadcast. IPv4 has checksum fields while IPv6 doesn't have checksum fields. IPv4 supports VLSM (Virtual Length Subnet Mask) whereas IPv6 doesn't support VLSM.

Nearly all the IP addresses in use today are IPv4, for "version 4." The number is a unique code the Internet uses to connect us all. Your IP address identifies both the type of network you're part of as well as your individual "host" or computer. Every computer that's online at any one time has a unique IP address.

2 Answers. IPv4 and IPv6 are two completely separate protocols, with separate, incompatible packet headers and addressing, and an IPv4-only host cannot directly communicate with an IPv6-only host. The correct way to do this is to dual-stack one or both hosts so that they run both the IPv4 and IPv6 protocols.
