There is no difference between those two. Just a different way
to encode the same thing.

Yes, but NTP does not have to. NTP can just open an IPv6 socket and
shove all IPv6 and IPv4 in through that socket. Apache does this,
sendmail does this, nginx does this, postfix does this. Very standard
and very easy.

know routing. Unless, of coure, they are routing daemons.
