BTCL Expands DNSSEC Deployment to .com.bd and .net.bd

Bangladesh Telecommunications Company Limited (BTCL) is pleased to announce the successful implementation of Domain Name System Security Extensions (DNSSEC) for the .com.bd and .net.bd zones. This marks another significant milestone in our ongoing commitment to strengthening the security and resilience of the national DNS infrastructure.

DNSSEC adds a vital layer of trust to the Domain Name System by enabling cryptographic validation of DNS responses. This ensures that users reach the authentic websites they intend to visit and protects against threats such as cache poisoning, man-in-the-middle attacks, and domain hijacking.

BTCL previously enabled DNSSEC for .ac.bd and .gov.bd, setting a strong foundation for secured digital services across academic and government institutions. Extending DNSSEC to the highly used commercial zones represents the next strategic step in safeguarding Bangladesh’s digital ecosystem.

What This Means for Users and Registrants

-Enhanced Integrity: DNS data is digitally signed, preventing tampering or unauthorized modification.

-Greater Trust: Businesses and service providers under .com.bd and .net.bd can now ensure a more secure user experience.

-Stronger National Infrastructure: With more secure DNS zones, Bangladesh moves closer to global best practices in Internet security and governance.

BTCL’s Ongoing Commitment

As the operator of the .bd and .বাংলা country code domains, BTCL remains dedicated to modernizing core Internet infrastructure and aligning with global technical standards such as DNSSEC, IPv6, IDN, and Universal Acceptance.

The extension of DNSSEC to .com.bd and .net.bd reinforces our responsibility to provide secure and resilient domain name services for all stakeholders—government, business, academia, and the general public.

We thank our technical team and partners for their continuous effort, innovation, and dedication to improving the security posture of the nation’s DNS system.
