The root zone file presently contains 251 domains.
However ZR. is transitioning to CD. (Zaire to Dem Rep Congo),
so there are effectively only 250.
ISO 3166-1:1997 as of 7 Apr 99 contains 238 codes.
One of the 238 is not contained in the root zone -
North Korea.
The 13 other domains in the root zone are:
ARPA.
AC. Ascension Island
COM.
GOV.
GG. Guernsey
INT.
IM. Isle of Man
JE. Jersey
MIL.
NET.
ORG.
SU. Soviet Union
UK. United Kingdom
Query: since ccTLDs are by definition tied
to 3166-1, what are AC, GG, IM, JE, SU, and UK ?
