The .bd domain is the Internet country code top-level domain (ccTLD) for Bangladesh. This particular top-level domain is managed and administratively operated by Bangladesh Telecommunications Company Ltd (BTCL), which is designated as the official domain registrar for .bd domains.
The .bd domain comprises different second-level domains. The primary subdivisions of the .bd domain include .com.bd for commercial enterprises, .edu.bd for educational institutions, .ac.bd for academic research-based organizations, .net.bd for network service providers or ISPs, .gov.bd for government organizations, and .org.bd for non-profit organizations. These particular classifications enable systematic organization, making it easy to identify the nature of a site hosted under this top-level domain.
Internet Assigned Numbers Authority (IANA) has delegated the sponsorship and operational management of .bd domain to BTCL. BTCL is responsible for the policy and operation of the .bd domain, and handles all the DNS management, zone file generation, and subdomain delegations.
Domain name registration under the .bd top-level domain requires local presence in Bangladesh. This requisite ensures that companies or organizations with the .bd domain have valid local active contact addresses. This restrictiveness can help prevent cyber squatting, ensuring that the .bd domains are utilized responsibly and functionally.
It is interesting to note that BTCL has put in place DNSSEC (Domain Name System Security Extensions) for the .bd domain. DNSSEC provides additional security by enabling the .bd domain to be resistant to certain types of attacks such as Domain Name System spoofing and cache poisoning. It assures that Internet users reach the correct site when they type in a .bd domain in the address bar.
In terms of the technical upkeep, the .bd domain undergoes routine maintenance to continuously improve its performance and security features. This maintenance involves undertaking updates in both hardware and software infrastructure, monitoring, troubleshooting, and taking pre-emptive actions as necessary. As such, the .bd domain has a relatively high degree of stability and dependability.
Some examples of .bd domains include dse.com.bd, probashi.gov.bd, and mujib100.gov.bd, which belong to the Dhaka Stock Exchange, The Ministry of Expatriates’ Welfare and Overseas Employment, and the Government of Bangladesh’s dedicated site for the observance of the birth centenary of the nation’s founder.
