DDClient questions

So I run a pi hole dns server on a small rock64 board and since it uses little resources, I decided to add a ddclient to keep my dnsomatic collection of domains up to date.  I have comcast and it didn't change my IP for years but recently it changed twice so I figured I better do this.

Setup was simple and the config worked after some minor tweaks and setup the daemon to update once an hour.

On occasion I get some warnings about not being able to find an ipv4 or ipv6 address.  If I run the ddclient -verbose command a few times, it will sometimes succeed, other times I see the same Warning error.  Normal activity?
