Summary

LCH

United Kingdom · AI-generated

business finance clearing corporate

LCH-CLEARNET is operated by LCH Group Holdings Limited.

What it's used for

  • The space carries internal corporate infrastructure, identified by the netname LCH-CLEARNET and registrant LCH Group Holdings Limited.
  • The AS announces a single IPv4 prefix, 195.246.228.0/23, comprising 512 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the address inventory is finely subdivided for a single corporate entity, indicating an internal estate rather than an access or transit network.
  • Traffic from this AS consists of internal systems for a global financial clearing house, supporting clearing, settlement, and margining operations for derivatives and exchange-traded products.

Notable

  • The RDAP registrant LCH Group Holdings Limited matches the AS handle and the known operator.
  • LCH.Clearnet Ltd was rebranded as LCH in 2016, and the parent company is majority-owned by the London Stock Exchange Group plc.
  • The inventory consists of a single contiguous /23 block, consistent with a dedicated corporate allocation.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
