It does look very internal, but the root domain name is more comprehensible than it might appear.

Cequint is a company that provides caller ID services. "Vz" is short for Verizon. "Cid" is short for caller ID. That only leaves "we", which probably refers to either "wireless" or "web" in some way, e.g. wireless/web "edge" or "endpoint".

The domain is therefore the Cequint Verizon Wireless (Web?) Edge Caller ID endpoint.

I don't know what clr or aqx are, though. (I assume CLR is not Microsoft's Common Language Runtime, but I suppose it could be. I know at least one company that likes to name services after the technology used to implement them.)
