Autonomous system
AS13359 LEARN-CACHING-PEERING
Unclassified ARIN
Summary
LEARN
education research infrastructure
The AS handle names the job rather than the owner: caching and peering.
What it's used for
- A research and education network. 256 addresses in one IPv4 prefix,
74.200.189.0/24, fifteen observed BGP neighbours, and the IPv6 block2607:f928:4::/48.
Notable
- The AS handle is
LEARN-CACHING-PEERING. - The block's netname is
LEARN, registered to the network and its operations centre. - Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Almost every AS handle is a company name or its initials. This one is a job description, which means the organisation runs more than one autonomous system and needed to tell them apart by function. Separating the peering and caching system from the main network lets it be advertised to exchange partners without exposing anything else.
- A single /24 against fifteen neighbours is the shape of that job exactly. The address space exists to give the caches and the peering routers somewhere to live; the value is entirely in the adjacencies.
- Research networks build these because content caches sit physically inside their campuses. Traffic that would otherwise cross paid transit is served from a rack down the hall, and the peering system is what makes the rest of the internet aware of 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: 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.
