dnscache Log File Format
by Rob Mayoff These notes are incomplete. dnscache is part of the djbdns package, written by Daniel J. Bernstein, aka djb. I couldn't find any documentation on its log file format, other than this explanation of one field of the stats log entry. This file contains my notes on what the log entries mean. If there are any errors here, they are mine and not djb's. dnscache logs IP addresses as 8 digit
