About this network

A netname date with seven digits, where the month was written without its leading zero.

What it's used for

• A German regional carrier routing for a group of municipal utilities. 142,080 addresses across 33 IPv4 prefixes, four IPv6 prefixes, and 185 observed BGP neighbours.

Notable

• One netname reads DE-TNGSTADTNETZ-2000308: seven digits, not the usual six or eight.
• Others are dated 19951017, 19960104, 19990830, 20001121, 20021009 and 20050602.
• Registrants include five separate municipal utility companies alongside the carrier itself.
• Seven of 18 sampled addresses returned names across three domains, including 0.8.93.62.dsl.xitylight.de, whose octets are reversed.

Interesting

• Seven digits can only be a date whose month was written as a single character. It is the same eight-digit convention with a leading zero dropped, and it proves the field is typed by hand rather than generated. Nothing validated it then and nothing has corrected it since.
• Eight-digit dates from 1995 and 1996 sit here beside six-digit ones elsewhere in this range. The two forms were never sequential eras; both were in use throughout.
• Five town utility companies routing through one carrier is the German municipal model in a single record. Each utility holds its own space under its own name, and the carrier supplies the path.
