Summary

SwissIX

Switzerland · AI-generated

exchange transit infrastructure switzerland

SWISSIX is the AS handle for SwissIX Internet Exchange.

What it's used for

  • The address space carries infrastructure for the Swiss Internet Exchange, evidenced by netnames CH-SWISSIX-20170921 and SWISSIX and reverse DNS entries pointing to anchors.atlas.ripe.net.
  • With 1280 IPv4 addresses and 2 IPv6 prefixes announced against 210 observed neighbours, the high neighbour-to-address ratio indicates a transit or peering role rather than an access network.

Notable

  • Registrants for both announced prefixes are consistently listed as SwissIX Internet Exchange, matching the AS holder.
  • The inventory consists of two IPv4 prefixes (185.222.12.0/22 and 194.242.34.0/24) and two IPv6 prefixes, representing a compact estate typical for an exchange point's own infrastructure.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
