Ipv4 is the current version of IP protocols. Ipv6 is a new addressing scheme and protocol. It has a 128 bit address space instead of the current 32 bits. It's eventually going to replace Ipv4. But first there is going to be a rather lengthy transition period. Microsoft is working on a IPv6 protocol stack for it's NT products, and Linux has IPv6 in the 2.1.x series kernels. IPv6 also has some features that are going to be more multicast friendly, and will allow for prioritizing of packets. Hope this helps clear things up somewhat. -Matt Gabe wrote: > > I hope I don't sound clueless, but what exactly is IPv6 and IPv4?
