Hello, I have gone through a lot of literacture regarding IPv6, but the issue regarding compatibility addresses and there usage is still unclear. There are three types of these "compatibility addresses" for coexistance of IPv4 with v6 (or so i am told). 1) IPv4 compatable address i.e. ::a.b.c.d where a.b.c.d is the v4 address. 2) IPv4 mapped address i.e. ::FFFF:a.b.c.d. 3) 6to4 address 2002:(a.b.c.d in Hex)::.
Can somebody please explain when each particular address is used. I know that 6to4 address are defined to tunnel v6 data over a v4 network. but does this mean that with this IPv6 address when we send on a v6 socket (opened previously) the stack itself encapsulates that in a v4 address (extracted from IPv6 address)? If so how does the stack(v4 stack will get it right?) cahnnel it to the correct v6 socket? The use of first two addresses, on the other hand, is totally unknow to me. All and any help would be much appreciated. Affan Ahmed. __________________________________________________ Do You Yahoo!? Yahoo!
