TLD List

This is a list of all TLD (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 doesn't seem to be a good list.

See

• http://en.wikipedia.org/wiki/List_of_Internet_top-level_domains
• http://www.neuhaus.com/domaincheck/domain_list.htm

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
