The problem is that .internal is the bureaucratically correct answer, and not all internal networks are LANs.

Maybe they can reserve both .interNAL and its convenient abbreviation, which just happens to be written backwards because it's DNS.

Answer is simple and straightforward - nothing like this is going to happen because short abbreviations and any potential short alternatives can be sold and sweet sweet money can be extracted

Ha, excellent

Submitted to ICANN; everybody keep yelling .interNAL until it happens!
