About this network

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.
