Bangladesh · AI-generated

isp fiber residential bangladesh

DFN-BD is operated by Dhaka Fiber Net Limited.

What it's used for

  • The address space carries residential and business internet access, with netnames including DFN-BD, DFNMEDIA-BD, CRESCENT-AS-AP, and IRT-BON-BD.
  • The AS announces 4,864 IPv4 addresses across 7 prefixes and 87 IPv6 prefixes, maintaining 4 observed neighbours; this ratio indicates an access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for high-speed fiber-optic broadband services in Dhaka, supporting streaming, gaming, and remote work.

Notable

  • Registrants for the largest prefixes are consistent with the announcer, listing Dhaka Fiber Net Ltd, DFN Media, Bondhon Online Network, Crescent Network, and Unitech Internet.
  • The inventory includes a mix of /22 and /24 blocks, with some prefixes registered to distinct entities like DFN Media and Unitech Internet, suggesting internal segmentation or acquired space.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,782 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
