AS16050 REFINITIV-SLOUGH-LO5-RES-AS Refinitiv Slough-LO5 resiliancy
Unclassified RIPE
Summary
Refinitiv (Slough)
finance media infrastructure
The handle names a town, a site code, and a purpose, with the word for resilience misspelled.
What it's used for
- A market data company's site network. Nineteen IPv4 prefixes announced from the United Kingdom, no IPv6, ten thousand seven hundred and fifty-two addresses, across four observed BGP neighbours.
Notable
- The handle is the brand, a town, a three-character site code, a contraction for resilience, and three letters for an autonomous system. The word for resilience is spelled with an extra letter.
- Netnames use four conventions at once: the brand's initials with a base address and a sequence digit, the brand's initials with the site code, three initials with a number, and the full brand with a base address and prefix length written out.
- Most blocks are registered to the group's company in another country entirely, despite being announced from this one. One is registered to a third national arm.
- One block belongs to the parent exchange group's handle, built from initials, a town contraction and a country code. Another's abuse contact is a numbered role with a four-digit number.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Naming an autonomous system after one building's backup path is unusual and precise. It says this number exists to keep a specific site reachable when its primary path fails, not to serve a business.
- A typo in the handle has been carried in every routing lookup of this network for years, because the field is a label and nothing validates the spelling of a label.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
