About this network

Netnames that spell an address range out in words, and a function split written in two languages.

What it's used for

• A small German hosting and network operator. 2,048 addresses across five IPv4 prefixes, one IPv6 prefix, and 90 observed BGP neighbours.

Notable

• Netnames are DE-SERVE-U-20180108, KIEZ-70-141, KIEZ-73-to-92, FMT32-Core and FMT32-Kunden.
• Three blocks are registered to a named individual and a separate network operations contact.
• The IPv6 announcement is a /29, far larger than the IPv4 footprint.
• One of 15 sampled addresses returned a name: serve-u-on-the-road.FMT32.NET.

Interesting

• KIEZ-73-to-92 writes a range using the English word to inside an identifier, where every other netname in this range uses hyphens or nothing. It reads as a note to a human rather than a label for a system, which is what netnames actually are: free text nobody parses.
• FMT32-Core and FMT32-Kunden split infrastructure from customer space using an English word and a German one in the same pair. Both were obvious to whoever wrote them, and neither is obvious together.
• Ninety BGP neighbours against 2,048 addresses is an operator that peers far more widely than its own address count would suggest. The interesting number here is the peering, not the space.
