BIND 9 needs both forward and reverse

Interestingly, this would appear to tie in with a problem our customers have
with querying the name servers belonging to fasthosts.co.uk
If anyone wants to try, use a Bind 9.1.0 server to:
dig fasthosts.co.uk soa
then try the same thing on a Bind 8.x server
dns.fasthosts.co.uk does not have reverse.
Cheers,
Owen
