192.2.0.55 has a TLD... 55.
dig 192.2.0.55
what name have the nic ns then ?
None. That's actually my entire point.
Since the 55 TLD doesn't exist, you get a NXDOMAIN from the
root-servers and reject the mail.
you could say it that way yes, but its still incorrect
How is that incorrect? The RFCs specify how to describe an address
literal, anything else should be treated as a domain name. 192.2.0.55 is
no different than hello.example or
aaaaaaaaaaaaaaathisisjustanexample20131030.com, both the MX and A record
lookups return a NXDOMAIN, and so the mail is not deliverable.
