Thanks byte, but "dig @ns1.dyndns.org -x someip +short +norecurse" returns blank, and I know that IP is registered with dyndns. Thanks, Adrian On Thu, Jun 25, 2009 at 2:14 PM, <byte.bucket at 4a44.com> wrote:
Does anyone know a way to specify a reverse DNS look up against aspecificDNS 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.
