AS5459 LINX-AS London interconnection point
Unclassified RIPE
Summary
London Internet Exchange (LINX)
ixp network legacy
LINX-AS, described in the registry simply as the London interconnection point — the London Internet Exchange, one of the largest and oldest internet exchange points in the world.
What it's used for
- LINX's own infrastructure and services as an exchange operator: the address space underpinning its peering fabric and the systems that run it.
Notable
- An IXP's ASN is not a transit network. Members exchange traffic directly with each other over the exchange fabric, each under its own AS number; LINX itself is the venue, not a hop in the path. LINX's route servers, which do mediate peering between members, run under a separate ASN.
- LINX was founded in the mid-1990s by a handful of UK ISPs who wanted to keep domestic traffic in the country instead of hauling it across the Atlantic and back. The low AS number dates from that period.
Interesting
- The "keep local traffic local" argument that started LINX is the same one every IXP has made since. It is why an AS number attached to a building full of cross-connects ended up among the most consequential on the list.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 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.
