[ale] Anybody familiar with dyndns client, "addns.pl"?

[Marvin, International Martian of Mystery]

I keep getting this message whenever I try to update dns:

root at mrpooter:/home/dabaron/addns-1.2# addns.pl --detect_host
iface: system type not specified, using default - "dyndns"
iface: performing update, ip=71.56.13.176
iface: failed update (removing from list): Host mrpooter.homelinux.net 
blocked for abuse

Anybody have a clue as to what's going on here?
