Summary

Security Monitoring Centre

Netherlands · AI-generated

security monitoring business

SMC is operated by Security Monitoring Centre B.V.

What it's used for

  • The address space carries infrastructure for alarm monitoring and response services, as indicated by the netname SMC and registrant Security Monitoring Centre B.V.
  • The AS announces 256 IPv4 addresses within a single prefix (91.209.110.0/24) and maintains 2 observed neighbours, indicating a small, self-contained business network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of web endpoints and signalling for the company's global alarm monitoring and response operations.

Notable

  • The RDAP registrant Security Monitoring Centre B.V. matches the AS holder, confirming consistent ownership of the address space.
  • Security Monitoring Centre B.V. is part of UTC Fire & Security, a global provider of security and fire protection solutions.
  • The inventory consists of a single /24 block in the Netherlands, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
