Summary

Legal & General Investment Management

United Kingdom · AI-generated

business finance corporate

LGIM is the autonomous system for Legal & General Investment Management Holdings Ltd.

What it's used for

  • The address space carries corporate infrastructure for the asset management division of Legal & General, with netnames LGNET and LGIM-NET registered to Legal & General Resources Ltd and Legal & General Investment Management Holdings Ltd.
  • The AS announces 1280 IPv4 addresses across 3 prefixes and maintains a single observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and web endpoints for the investment management business, not subscriber or customer traffic.

Notable

  • Registrants align with the announcer, with Legal & General Resources Ltd holding the LGNET prefixes and Legal & General Investment Management Holdings Ltd holding the LGIM-NET prefix.
  • The address inventory is finely subdivided into three distinct blocks, consistent with internal site-by-site segmentation for a large corporate entity.

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: 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.
