2.2 - DHCP -strange .dyndns forward map not found on DHCPACK

[2chemlud]

Hi there!

Was having a look at my DHCP log and found that after each DHCPACK message there is a "unable to add forward map" to a somewhat strange .dyndns.org domain (made from the hostname acknowledged and adding .dyndns.org).

I have a dyndns service set up, but not at dyndns.org. What's that?

Kind regards
