domains Which Top Level Domains have an IP address?

Does the hyperlink http://dk/ work? Yes. How? Because .dk (Denmark) is one of the rare Top Level Domains (TLDs) to have an IP address.

As you can see from DNS clients like dig, as well as online services like DNS Looking Glass, the .dk (Denmark) TLD has an IP address. Something that is both mundane (assigning IP addresses to names is one of the main uses of DNS) and rare, because TLDs usually do not contain information, but transfer to second-level domains.

Which Top Level Domains have an IP address?

• .ai (Anguilla)
• .bh (Bahrain)
• .cm (Cameroon)
• .dk (Denmark, already mentioned)
• .gg (Guernsey)
• .je (Jersey)
• .pn (Pitcairn)
• .tk (Tokelau)
• .uz (Uzbekistan)
• .va (Vatican)
• .ws (Samoa)
• .мон (Mongolia)

Note that none of the TLDs managed by ICANN appear in this list. This is because ICANN prohibits the allocation of an IP address at the apex (the root of a DNS zone). See “Applicant Guidebook”, section 2.2.3.3, “TLD Zone Contents”.
