About this network

Netnames encoding a date, a counter and a country code, with a stem that changes length each time.

What it's used for

• A regional telephone and internet group. Fifty-five IPv4 prefixes announced from Canada, forty-eight thousand addresses, across two observed BGP neighbours.

Notable

• Three blocks carry netnames built from a stem, a five digit number, a fixed six digit code, a small number, an eight digit date and a country code, and the stem is written three different lengths in three otherwise identical labels.
• Several blocks carry the group's netname while being registered to a different telecommunications company, so the label and the owner disagree by design.
• Another company's blocks use their own short netname, keeping their identity inside the group's routing.
• Reverse names combine a letter and digit prefix, the full address, a dynamic or static marker, and a three or four letter town code before the group's domain.
• One block's registry lookup failed, so nothing can be said about who holds it.

Interesting

• The town codes make the reverse names a map. Each answer says which exchange the subscriber is on, which is how a support desk triages a fault and also how an outsider infers the network's geography.
• Dates in netnames are provisioning receipts, and the varying stem length shows they are typed rather than generated. Three attempts at the same format produced three different results.
• A group assembled from smaller carriers shows up as exactly this: one netname where the paperwork was updated, the original one where it was not.
