BTCL currently does not allow registering a domain directly under Dot BD. That must be a subdomain under several Dot BD extensions. For example "abc.bd" for a certain company "abc" is not allowed. But a domain of the form "abc.com.bd" or "abc.net.bd" is valid.
Presently com.bd, co.bd, edu.bd, ac.bd, net.bd, gov.bd, info.bd, tv.bd, ws.bd, org.bd, mil.bd sub domains are available. But "gov" and "mil" sub domains are reserved for "Government" and “Defense" organizations respectively. Registration of domains under such domains should be initiated by appropriate authority.
Here is a table for extensions, areas and Registration qualifications:
|Domains and Subdomains||Areas||Registration qualifications.|
|.com.bd||Commercial||Organizations or individuals.|
|.edu.bd||Educational sector||Educational institutes.|
|.co.bd||Commercial||Organizations or individuals.|
