Checking the list of ccTLDs at IANA, I found that more ccTLDs are not assigned neither:
- The .BQ for BONAIRE, SINT EUSTATIUS AND SABA;
- The .EH for WESTERN SAHARA;
- The .MF :-) for SAINT MARTIN (FRENCH PART);
- The .SS for SOUTH SUDAN;
- The .UM for UNITED STATES MINOR OUTLYING ISLANDS.
Some IDNs are not assigned yet neither.
