Summary

New Knoxville Telephone Company

United States of America · AI-generated

residential isp ohio telecom

NKTC is the autonomous system for New Knoxville Telephone Company, a regional telecommunications provider based in New Knoxville, Ohio.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS records pointing to nktelco.net and netnames such as NKTC and NKT-NETWORK-4.
  • With 28,672 IPv4 addresses announced across 11 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are listed as NEW KNOXVILLE TELEPHONE COMPANY, fully agreeing with the AS holder.
  • The address inventory consists of multiple /20, /21, and /22 blocks, including a large /19 block at 206.51.160.0/19, reflecting a finely subdivided corporate estate typical of a local exchange carrier.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
