Getting a List of Top-Level Domains
1.4.1 Problem
You need a list of top-level domains (TLDs), possibly to figure out which one your organization belongs in.
1.4.2 Solution
See http://www.norid.no/domreg.html for an alphabetical list of top-level domains. See http://www.norid.no/domreg-alpha.html for a list of top-level domains alphabetized by country name (instead of the top-level domain label). Each list includes links to the registration authority for each TLD.
1.4.3 Discussion
The most recent edition of DNS and BIND, as of this writing, also contains a list of top-level domains as its Appendix A. However, that list does not include the new generic top-level domains (e.g., biz and info), as they were introduced after that edition's publication.
