Yes, but 'host debian.pool.ntp.org' shouldn't just return nothing should it?
To my knowledge there's no requirement that higher level domains should resolve. (For example, that would imply that you should be able to resolve "org" before you can resolve "ntp.org".)
No, I agree, but it shouldn't return 'nothing' should it? Non-existent domains return NXDOMAIN.
The domain is not non existent - the A record is empty.
OK, but the 'successful' lookup with no result could confuse some software couldn't it? dig shows 'NOERROR', host returns nothing, nslookup says "*** Can't find debian.pool.ntp.org: No answer", it's not very consistent. :-)
Different tools will often give apparently different answers. But they are consistent.
Take a look at the full response to a dig query. It clearly shows no A record.
