well it's official RIPE policy (presumably initiated from IANA) that
ISPs should use private address space for point to point links and
for interfaces that do need to be globally addressable.

what is it? if it's a PTP link then that's fine - however i don't
think it should be published in DNS.  (see kenn's mail).

prefectly legal. (although really you should see * * * in the
traceroute - if you see 10/8, 172.16/12 or 192.168/16 then all the
routers between you and the router using those private ips are
misconfigured).

that was something different. in the end i went with bind 9 and split
DNS.

NB: never ever implement split DNS if you can avoid it.
