That's almost as bad as the hundreds of subdomains used in webpages 
which sometimes hit broken load balancers (reporting nxdomain for AAAA). 

Very few do that anymore.  What they do however is return the wrong SOA
record.

So you have to check each and every domain in the source to find which 
ones are broken.

Which one really shouldn't have to do.  Add DS-Lite support to the
phone and have the carriers advertise that they support DS-Lite and
the IPv4 literal problem goes away.

This has been done in a phone already so it is possible to do.
