Summary
Bhairab Express Net
isp residential legacy
AS9451 (BEN-AS-AP) is held by Bhairab Express Net, a small broadband internet service provider based in Bhairab, in the Kishoreganj district of Bangladesh. It is a local access ISP: one town's worth of subscribers, not a regional carrier.
What it's used for
The routing footprint matches the business exactly. RIS observes 3 IPv4 prefixes covering 512 addresses — a single /23 (45.112.74.0/23) plus the two /24s it decomposes into, which is a routine traffic-engineering deaggregation rather than three separate allocations. There is no IPv6 announced at all, and just 1 observed BGP neighbour, meaning the whole network hangs off a single upstream transit provider.
That combination is the classic shape of a last-mile ISP at the bottom of the food chain: a couple of hundred routable addresses, almost certainly fronting a much larger pool of subscribers behind carrier-grade NAT, and no peering relationships of its own. A wholesale carrier of any kind would show tens or hundreds of neighbours; an eyeball network this size shows one, because it buys transit and resells access. Bangladesh's ISP market has a long tail of exactly these town-level operators, each holding a legacy ASN and a single small allocation.
Notable
- The
45.112.74.0/23allocation is APNIC space assigned well after the AS number itself, so the low ASN says nothing about how long this particular network has been announcing routes. - No IPv6 deployment is visible in RIS, which is common among small South Asian access providers.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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