Summary

AIG Europe (Services) Limited

United Kingdom · AI-generated

business corporate insurance internal

AIG-EUROPE-SERVICES-LTD is held by AIG Europe (Services) Limited, the European services subsidiary of American International Group.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the consistent netname AIGI and registrant American International Group, Inc.; Global Network Engineering across all announced prefixes.
  • The AS announces 1536 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, with 5 observed neighbours; this low neighbour count relative to the address inventory indicates an internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers, internal applications, and backhaul for AIG's European operations, consistent with the company's business in insurance and risk management services.

Notable

  • Registrants agree with the announcer, with all RDAP entries listing American International Group, Inc.; Global Network Engineering as the registrant.
  • The address inventory is finely subdivided into five /24 and /23 blocks within the 167.247.0.0/16 range, reflecting site-by-site segmentation typical of large corporate networks.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
