DNS look up against a specific DNS provider

Thanks byte, but "dig @ns1.dyndns.org  -x someip +short +norecurse" returns
blank, and I know that IP is registered with dyndns.

Thanks,
Adrian

Does anyone know a way to specify a reverse DNS look up against a
specific
DNS provider? I don't want to use the DNS that is authoritive for  the
given
IP range. For example, look up all of the IPs at my org to see if any are
mapped to some host name at DYNDNS? Some bot nets use these services for
naming, so I thought this might be useful.

Try one of the following from your favorite *nix variant:

$  dig @{server you want to query} -x {ip address} +short +norecurse

or

$ host -r {ip address} {server you want to query}



Windows nslookup is kind of pathetic but I believe you can do the same
with it as follows:

C:\> nslookup -norecurse {ip address} {server you want to query}
