Summary
Grameen Cybernet
isp residential bangladesh cable
CYBERNET-BD-AS is operated by Grameen Cybernet Ltd., a Bangladeshi internet service provider based in Dhaka.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
M01176B.citech-bd.comand254.186.83.203.grameencybernet.net. - The AS announces 14,080 IPv4 addresses across 14 prefixes and 1 IPv6 prefix, while maintaining only 3 observed routing neighbours, a ratio characteristic of an access network rather than a transit provider.
Notable
- All registrants in the RDAP data align with the announcer, consistently listing
IRT-CYBERNET-BDandGRAMEEN CYBERNETfor the netnameCYBERNET-BD. - The inventory is composed of multiple /20, /21, /22, /23, and /24 blocks, primarily within the 203.83.0.0/16 and 202.125.0.0/16 ranges, indicating a fragmented but cohesive corporate estate.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
