About this network

A Swiss hosting company with one IPv4 block and forty BGP neighbours.

What it's used for

• Hosting. 2,048 addresses in a single /21, one IPv6 /32, and forty observed BGP neighbours.

Notable

• The one IPv4 prefix, 93.189.64.0/21, is netname CH-VIRTUALTEC-20080424, registered to Virtualtec Solutions AG.
• The IPv6 allocation is a /32, announced as one prefix.
• Reverse DNS answers as net66-0.virtualtec.ch, naming the subnet rather than the host.

Interesting

• Forty neighbours against 2,048 addresses inverts the usual reading. Address count measures how many things a network has; neighbour count measures how many other networks it talks to directly, and a ratio like this describes a company that peers rather than one that grows.
• Switzerland makes that easy. The exchange points in Zurich and Geneva let a small provider reach hundreds of networks over a single port, so the cost of a peering session falls to nearly nothing and the sensible number of neighbours becomes all of them. A /21 in Zurich can have the connectivity of a network many times its size.
