Summary

Bank Alfalah Ltd.

Bangladesh · AI-generated

bank business bangladesh

BANKALFALAHLTD-AS-AP is operated by Bank Alfalah Ltd.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname BANKALFALAHLTD-BD and registrant Bank Alfalah Ltd.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small-scale internal network rather than a transit or access provider
  • Traffic from this AS consists of office workers and internal banking systems for the bank's Bangladesh operations

Notable

  • Registrants for both prefixes (103.42.152.0/23 and 103.42.154.0/24) consistently identify Bank Alfalah Ltd. as the holder, matching the AS announcer
  • The address inventory is finely subdivided into two contiguous blocks, consistent with an internal corporate estate segmented by site or function

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
