Summary
Saskatoon Internet Exchange Inc (YXEIX)
hosting legacy
YXEIX-SRV is the services autonomous system of the Saskatoon Internet Exchange (YXEIX), the not-for-profit internet exchange point that has interconnected Saskatchewan networks since 2017. RIS sees 2 IPv4 prefixes (512 addresses), one IPv6 prefix (2602:f979::/40), and 5 observed BGP neighbours.
What it's used for
Not the exchange fabric itself — an IXP's peering LAN is not routed — but the services the exchange runs alongside it. That is what the -SRV in the handle means, and it is why this AS announces anything at all. Both /24s (23.128.92.0/24 and 207.89.50.0/24) register to Saskatoon Internet Exchange Inc itself, and the one sampled reverse-DNS record, windowsupdate.yxeix.ca, is characteristic of the workload: content and update caches parked at the exchange so member ISPs can pull large, repetitive downloads locally instead of over expensive long-haul transit. Route servers, looking glasses, measurement probes and member-facing infrastructure live in the same space. Five neighbours is consistent with a handful of participants and upstreams, not a transit business.
Notable
A low AS number here is not an old network. ARIN registered AS11655 to the Saskatoon Internet Exchange on 2 February 2024 — the number is recycled, returned from a previous holder and reissued, decades after four-digit ASNs were first handed out. The exchange itself only dates to 2017. This AS is a clean worked example of why an AS number cannot be read as a date of birth.
Getting local traffic to stay local is the entire point of a regional IXP: without one, two Saskatoon networks may only meet each other in Toronto or Chicago.

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 1,781 prefixes, as published 2026-10-16. 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.
