Summary

The City Bank (Bangladesh)

Bangladesh · AI-generated

enterprise legacy

AS9651 (THECITYBANK-BD) is held by The City Bank Limited, a commercial bank in Bangladesh. The registry object's odd-looking name — "Jibon Bima Tower (4th Floor)" — is simply the bank's street address: Jibon Bima Tower, 10 Dilkusha C/A, Motijheel, Dhaka, which is its principal office.

What it's used for

This is a bank's own enterprise network. RIS sees 4 IPv4 prefixes totalling 1,024 addresses and no IPv6, announced through 3 observed neighbours. The prefixes form two pairs — 103.29.104.0/24 and 103.29.105.0/24, plus 103.250.42.0/24 and 103.250.43.0/24 — so the whole inventory is two /23-sized assignments split into /24s, both out of APNIC's 103.0.0.0/8 block.

A thousand addresses behind three upstreams is not a service-provider shape; it is a corporate multihoming shape. For a bank the motivation is availability rather than capacity: branch connectivity, internet banking front-ends, ATM and card-switch links all need to stay reachable if one Bangladeshi transit provider has a bad day, and owning the ASN and the addresses means the bank can move between carriers without renumbering anything. The very small address count also implies most of the bank's estate is behind NAT or on private networks, with only public-facing services and gateways occupying routable space.

Notable

  • The AS name looks like a building, not a company. It is a common APNIC-object quirk where the address line has ended up as the org description.
  • Both blocks come from 103/8, a relatively late APNIC allocation, so the addressing is newer than the low ASN suggests.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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.
