Autonomous system
AS15814 AS15814 CS - Autonomous System
Unclassified RIPE
Summary

The one host that answers is called a development machine, on a domain belonging to nobody in the record.
What it's used for
- A securities settlement company's network. Seven IPv4 prefixes and one IPv6
/32announced from Luxembourg, four thousand and ninety-six addresses, across eleven observed BGP neighbours.
Notable
- Of eighteen addresses queried, one returned a name, and that name begins with the three letters for development on a domain that matches neither the holder nor any netname.
- All seven blocks share one netname: the parent exchange group's four initials, a hyphen, and the subsidiary's name in mixed case.
- The AS handle is the two letters for an autonomous system with this number attached, then the subsidiary's two initials, then a hyphen with spaces around it, then the words for an autonomous system spelled out.
- Every block comes from one range, split into two prefixes of one size, three of the next and two of the smallest, with no covering route.
- Eleven neighbours for four thousand addresses is high, which suits a business its counterparties must all be able to reach.
Interesting
- Post-trade settlement is the plumbing under a stock exchange: the part that moves the securities and the money after the price is agreed. It needs very few addresses and a great many people able to reach them.
- A machine named for development is the sort of host that outlives the project that needed it.

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.
