You said "suspect" but do you have any evidence?

As I understand it, DNSWL lists IP addresses, not domains, but it only
lists addresses associated with validated domains. From the query
viewpoint, though, you just look up an address.

I do know that you can't associate an IP address with a domain, if those
IP addresses are already associated with some other domain.  But you're
not having that issue.

It seems that you can associate multiple domains with a single dnswl id,
but I don't have that problem so I haven't read the docs.


I would suggest waiting until you understand better to take more steps.
Probably you will get other advice too.
