Summary

Northwestel

Canada · AI-generated

residential telecom canada

The AS handle NWTEL is operated by Northwestel Inc., a telecommunications provider serving the Yukon and Northwest Territories.

What it's used for

  • The address space carries residential and business customer traffic, evidenced by reverse DNS records such as d207-189-235-254.yt.northwestel.net and netnames like NW-TEL-3 and NW-TEL-7.
  • With 30,976 IPv4 addresses announced across 40 prefixes and only 4 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Most registrants align with the announcer, identified as Northwestel Inc., though one prefix (199.247.52.0/22) is registered to Tamarack Computers Ltd. and another (207.148.48.0/21) to American Registry for Internet Numbers.
  • The inventory consists entirely of IPv4 space with no IPv6 prefixes announced, reflecting a legacy or IPv4-centric deployment.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
