Summary

Reservation Telephone Cooperative

United States of America · AI-generated

rural telecom cooperative north-dakota

RESTEL-81 is operated by Reservation Telephone Cooperative, a rural telecommunications provider based in Parshall, North Dakota.

What it's used for

  • The address space carries netnames such as RESTEL-POOL2, RESERVATION-TELEPHONE, and RESTEL-POOL3, indicating direct service to the cooperative's customer base.
  • With 18,688 IPv4 addresses announced across 22 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio implies an access or eyeball network rather than a transit provider.

Notable

  • Registrants include both Reservation Telephone Coop. and Dakota Carrier Network, with the latter holding several /23 and /24 blocks under netnames like DCN-NET-1 and DCN-NET-2.
  • The inventory is a mix of larger /20 blocks and numerous smaller /23 and /24 prefixes, suggesting a segmented internal estate or historical accumulation of leased space.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
