About this network

A Swedish hosting and connectivity provider.

What it's used for

• Hosting and colocation for business customers. 1,536 addresses over six /24s, three IPv6 announcements, five observed BGP neighbours.

Notable

• Six prefixes, four netnames. Two are plainly RESILANS; the others are FW-BG-NET, SE-MCA and NETCLEAN-NET, the last registered jointly with NetClean Technologies Sweden.
• Reverse DNS mixes the mechanical and the personal. Some addresses answer positionally as 64.resilans.se; others carry customer names — nic.inspectit.se and, on the same /24, quadlagge.languster.net.
• The abuse contact is registered as "Abuse handler 1000".

Interesting

• Every announcement is a /24, and no two are adjacent — 193.180.235, 194.14.3, 194.68.48, 194.71.2, 194.71.25, 194.71.117. That is a network assembled from whatever was available rather than allocated in one piece, which is the normal shape for a provider that grew after the large blocks were gone.
• Machines with names like quadlagge are a good sign about a hosting company. Positional reverse DNS is what you generate; a hostname somebody made up is what happens when the person running the server is a customer with an account rather than a row in a database.
