.bd
.bd is the Internet country code top-level domain ( ccTLD) for Bangladesh. It is administered by the Ministry of Post & Telecommunications of Bangladesh. Registrations are at the third level beneath several second-level labels, paralleling the oldest gTLDs; registration is open except in the gov and mil subdomains, which are limited to authorized entities in the Bangladesh government. There is no online registration facility available for .bd domains right now.
.বাংলা ("bangla") is a second country code top-level domain that was granted for Bangladesh in 2011. This domain is meant for web addresses in the Bengali language. The process of assigning domain names for web sites has not started as of 2014.
