See rfc 2460. Fragmented packets will have a fragment header. > > * * > > *Q2 What is the algorithm for scheduling at the router? Any standard?* I don't see why they would be different from IPv4.

IPv4-mapped addresses are an application porting mechanism that lets applications deal exclusively with IPv6 structures. -vlad --------------------------------------------------------------------- The IPv6 Users Mailing List Unsubscribe by sending "unsubscribe users" to [EMAIL PROTECTED]
