Summary

Xelon AG

Switzerland · AI-generated

hosting cloud switzerland

XELON is operated by Xelon AG.

What it's used for

  • The address space carries hosting and cloud infrastructure, evidenced by netnames such as CH-XELONHOSTING-20190719 and reverse DNS entries like 45-131-169-0.static.xelon.ch.
  • The AS announces 9,216 IPv4 addresses across 14 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a hosting or cloud provider role rather than transit.
  • Traffic from this AS consists of cloud workloads, virtual machines, and API endpoints hosted in Xelon's ISO-certified data centers in Switzerland.

Notable

  • Registrants for the majority of prefixes are Xelon NOC; Xelon AG; Abuse-C Role, which aligns with the AS holder. Two smaller prefixes (91.235.212.0/24 and 91.247.253.0/24) list individual registrants Matias Meier and Marco Kaelin respectively.
  • The address inventory is composed of multiple /22 and /24 blocks, with the largest being 45.131.168.0/22 and 109.106.16.0/22.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
