Do the internals of TCP change when it's running over IPv4 vs IPv6?
Does the interface to upper layers change?
Actually, yes - the pseudoheader over which the checksum is computed
channges. So too does ICMP signalling, setting of the DF bit for
fragmentation discovery (clearing it doesn't have the same effect in
v6
as in v4), etc.
...so, by analogy, there's likely a need to describe HTTP over different
