Summary

Bank Syariah Indonesia

Indonesia · AI-generated

banking business indonesia

BSM-AS-ID is held by PT. Bank Syariah Mandiri.

What it's used for

  • The address space carries corporate banking infrastructure, evidenced by netnames BSM-ID and IDNIC-BBSI-ID associated with registrants IRT-BSM-ID and IRT-BBSI-ID.
  • The AS announces 2048 IPv4 addresses across 5 prefixes and maintains 7 observed neighbours, a ratio consistent with a business network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate systems, branch backhaul, and web/API endpoints for the bank's digital services.

Notable

  • Registrants generally align with the announcer, with IRT-BSM-ID holding three prefixes and IRT-BBSI-ID holding one; one prefix is registered to ID-NIC HOSTMASTERS under the netname IANA-BLOCK.
  • PT. Bank Syariah Mandiri merged with Bank Mandiri's other Islamic banking unit and BNI Syariah to form Bank Syariah Indonesia.
  • The inventory consists of five distinct IPv4 blocks, including two /23s and three /24s, with no IPv6 prefixes in the inventory.

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: 447 networks and 1,843 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.
