AS14140 AUBURN-ESSENTIAL-SERVICES - Auburn Essential Services

Its netnames are full sentences naming the customer class, and its reverse names contain in-addr.arpa in the middle of the label.

What it's used for

• A community broadband network. 9,728 addresses across eight IPv4 prefixes plus one IPv6 prefix, 2607:1900::/32, with three observed BGP neighbours.

Notable

• Four blocks carry the netname AUBURN-ESSENTIAL-SERVICES, matching the registrant exactly.
• Three others spell out who lives there: AES-VOICE-SUBSCRIBERS---POTS---001, SMALL-BUSINESS-INTERNET-SUBSCRIBERS---002 and AES-RESIDENTIAL-INTERNET-SUBSCRIBERS---002, each with a matching descriptive registrant.
• Three of eighteen sampled addresses returned a name, all of the form 0-89-10-170.static.in-addr.arpa.elevatefiber.com.

Interesting

• Segmenting the registry record by customer class is unusual and generous. Anyone tracing abuse can tell a phone subscriber from a residential connection from a small business before sending a single packet, which is more than most carriers will say about their own space.
• The triple hyphens are a separator standing in for spaces and dashes the field cannot hold. The label is a sentence wearing a costume.
• Those reverse names carry in-addr.arpa as ordinary labels in the middle of a hostname. That is the signature of a zone file written without a trailing dot, so the resolver appended the domain to a name that was already complete. The address is reversed as well, so the mistake is visible twice over.
• A separate block for voice subscribers says this network sells telephone service, which is what happens when a community builds infrastructure rather than buying access.
