TLD List

This is a list of all TLDs (top-level-domains) with their policies for second and third level domains. This is to help with bug 319643, bug 252342, bug 8743, bug 66383, bug 264632, ... It will take some time to check every domain, since there isn't a good list available.

Type	Comment	Examples
A	Only second level domains	*.com, *.nl
B	Only third level domains	*.co.uk
C	Mixed second and third level domains	*.be, *.ac.be
D	Other

TLDs not in the root DNS

These are top-level domains that are not currently in the root DNS, and therefore have no domain names registered under them. However, some of them are currently in the ICANN approval process and may soon be added to the root DNS, therefore they are noted here so that the list above can be kept up-to-date.

TLD	Comments
ASIA	For Asian websites
EH	Western Sahara
KP	North Korea
ME	Montenegro
RS	Republic of Serbia
TEL	For telecommunications-related websites and services (overlaps with .mobi)

I'll start converting this list to the syntax defined in bug 331510, but I won't have time before the end of July --Jhermans 16:36, 10 June 2006 (PDT)

Over the next few months, I will start to update some of the details using information from the appropriate registries since I am helping out with the effective TLD list with a couple of other people. I have already added the .ax TLD and removed the .post one, which has not been approved and is not in the root DNS. --Rubena 15:37, 10 February 2007 (GMT)
