Hi all

Does anybody know how I could create a database function that accepts
an INET parameter and reverse-lookups the hostname via DNS PTR lookup?
Something like the dnsname command line utility in the djbdns package. I
need this function for analyzing firewall logs stored in the database
with ulogd.

Any idea would much be appreciated.

Regards
--Marcel
