Summary

North Dakota Telephone Co.

United States · AI-generated

isp telecom infrastructure

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.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
