Unclassified APNIC
Summary
LMAX Digital
business finance exchange infrastructure
EISCO is operated by LMAX Digital Group Limited.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by reverse DNS entries pointing to
lmax.comand netnamesJE-LMAXDIGITAL-20171206andJE-LMAXDIGITAL-20211115. - The AS announces 1280 IPv4 addresses across 2 prefixes while maintaining 70 observed neighbours, a ratio indicating a transit-heavy or highly interconnected internal estate rather than a residential access network.
- Traffic from this AS consists of institutional trading endpoints, market data feeds, and internal backhaul for LMAX Group's FX and cryptocurrency exchange operations.
Notable
- Registrants for both announced prefixes are listed as LMAX IS Networks and LMAX Digital Group Limited, aligning directly with the AS holder.
- LMAX Digital is the institutional cryptocurrency exchange division of LMAX Group, a global financial technology company operating regulated trading venues.
- The inventory consists of two distinct IPv4 blocks: 185.122.244.0/22 and 146.19.127.0/24, with no IPv6 prefixes currently announced.

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.
