.bw
.bw is the Internet country code top-level domain ( ccTLD) for Botswana. It is administered by the University of Botswana. There does not appear to be any official registry Web site or information online about how to register domains in this TLD, but some ISPs in Botswana offer this service, and it can be accomplished by filling out a form to send by paper mail. Most current registrations are at the third level beneath second-level names such as co.bw and org.bw, but some second-level registrations also exist. The most visited .bw domain is google.co.bw by Google Inc. in Botswana.
Botswana Telecommunications Corporation operates a WHOIS service for .bw domains.
