Sounds like logresolve or adnslogres to me ...
[cjwatson@arborlon ~]$ whatis logresolve
logresolve (8) - resolve hostnames for IP-adresses in Apache logfiles
[cjwatson@arborlon ~]$ zgrep adnslogres /usr/share/doc/libadns1-bin/README.gz
* adnslogres is a much faster version of Apache's logresolv program.
