Interesting Finds

Its a bit technical to explain, but if you have a *nix computer, and you look around in your named service config files (/etc/named.conf), you'll notice that 'localhost' refers you to a file at ( /var/named/chroot/var/named/localhost.zone) which contains the following information:

$TTL    86400
$ORIGIN localhost.
@              1D IN SOA       @ root (
                               42           ; serial (d. adams)
                               3H           ; refresh
                               15M          ; retry
                               1W           ; expiry
                               1D )         ; minimum

                1D IN NS        @
                1D IN A         127.0.0.1

Note the line with the number 42 and (d. adams) in the comment.
I find this highly amusing..
