List of all top level domains [closed]

Question

I found a lot of threads explaining how to get the country-codes in two- or three-letter format, but nothing that fits to my task. I'm heading for a way to get all the top level domains in an array or something. I know there's the CultureInfo class in C# but which could list the country codes. It doesn't include generic TLD, e.g.: "com". Here's the complete list of country codes I found.

Do you mean top level domain names (TLDs)? Both the two-letter geographical TLDs and the non-geographical ones? – Formulaic

Yes, I'm talking about the top level domain names. And yes, I need to get the geographical ones and the other ones. – Jasun

Note: .com is not a country-code top-level domain (ccTLD), but a generic top-level domain (gTLD). – Neoma

Answer 1

The authoritative list of all TLDs: http://www.iana.org/domains/root/db

The Root Zone Database represents the delegation details of top-level domains, including gTLDs such as .com, and country-code TLDs such as .uk.

You can get this as TXT, too (easier to parse): http://data.iana.org/TLD/tlds-alpha-by-domain.txt

Wikipedia also lists all TLDs, but it's not authoritative, of course: List of Internet top-level domains

---

The Mozilla Foundation maintains a Public Suffix List for effective top-level domains, i.e., those under which you can directly register names (for example .co.uk instead of .uk): http://publicsuffix.org/

See also tldextract, which handles this problem very well and uses Mozilla's PSL, as pointed out by @unor. It is in Python, but you may be able to glean the way it handles certain cases from its source code. (A win, because the problem domain is full of nuisances.) – Poole

the txt file only lists the TLDs but not whether they are country-codes or not. Do you know of a list that either provides this information or lists just TLDs of country-codes? – Islas

@IttayD: In case you missed it: the first link contains a table with the column "Type", where it says "country-code" for ccTLDs. – Neoma

@unor: i didn't miss, but parsing html is a pain – Islas

Answer 2

I like to use this list (it includes private TLDs): http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/effective_tld_names.dat?raw=1. To me it's the most complete list I could find and it's in a plain text format.

A lot more useful, since it includes TLDs like .co.uk etc – Colorific

Looks like the link is dead now unfortunately. – Schwaben
