So Cox are violating the RFC.
Perhaps you could direct them to the relevant RFC:
There are several TLD names which are reserved by RFC 2606, section 2.
Amongst them is the TLD "invalid".
<quote>
".invalid" is intended for use in online construction of domain
names that are sure to be invalid and which it is obvious at a
glance are invalid.
</quote>
Note the phrase "that are sure to be invalid".
An invalid domain name cannot have an IP address.
No DNS server should ever resolve addresses in the TLD "invalid".
