About this network

Every reverse name carries the town it serves, and the registrant on most blocks is a domain name rather than a company.

What it's used for

• A rural telephone company's broadband network. 30,464 addresses across 22 IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Most blocks are registered to goNDTC.com, under netnames running GONDTC-2 through GONDTC-70, plus one written out in full as GONDTC-66-163-128-0-20-NETWORK.
• Two blocks are registered to North Dakota Telephone Co. under NDTEL-NDTC and NDTEL-4, one of them alongside an ABUSE REPORTING contact.
• Twelve of eighteen sampled addresses returned a name, including drakedsl135255.gondtc.com, candodsl228000.gondtc.com, dvlknd-ai03-210000.gondtc.com and pnwbndai0184000.gondtc.com.
• The lookup for 76.10.96.0/22 failed, so nothing is known about that record.

Interesting

• Each label starts with an abbreviated town, then the service or equipment, then the last two octets padded to three figures each. Read one and you know where the line physically is, which is how a small operator with technicians in trucks wants its network named.
• The separators are inconsistent between eras: some labels use dashes between the parts and some run them together. The scheme was extended by hand as each exchange came online.
• A registrant field holding a domain name records the brand customers see rather than the company that files the paperwork. Both appear here, and only the tariffed telephone entity uses the legal name.
• Two neighbours carrying 22 prefixes is a network with no room for a bad day.
