About this network

One holder's netnames carry six-digit dates, eight-digit dates, and one that is eleven digits long.

What it's used for

• A regional broadband operator in Finland. 61,696 addresses across ten IPv4 prefixes, two IPv6 prefixes, and 29 observed BGP neighbours.

Notable

• Netnames include FI-KPO-990604, FI-KPO-20010322, FI-KPO-20140905 and FI-KPO-20020071112.
• One block is oulunkaari-seutuverkko, lowercase, with only an abuse role listed.
• Reverse names use three domains: kaisa-laajakaista.fi, kponet.fi and tutka.com.
• 213.143.168.0 answers with a name. Ten of eighteen sampled addresses returned one.

Interesting

• 20020071112 is eleven digits and cannot be a date in any format. It reads as a typed-in string that acquired an extra digit and was never checked, because nothing checks. Alongside the six-digit and eight-digit forms from the same holder, it settles that the date in a netname is decoration.
• The three reverse-DNS domains are three eras of branding surviving in parallel, with dyn and line- on the oldest naming a dial-up-era numbering scheme.
• 213.143.168.0 is the base address of a /24-shaped range and it has a name like any other, because the generator walks addresses and does not consult the routing table.
• 29 neighbours for a regional operator is a lot of peering for its size.
