Summary

isp telecom business infrastructure
Netnames encoding a date, a counter and a country code, with a stem that changes length each time.
What it's used for
- A regional telephone and internet group. Fifty-five IPv4 prefixes announced from Canada, forty-eight thousand addresses, across two observed BGP neighbours.
Notable
- Three blocks carry netnames built from a stem, a five digit number, a fixed six digit code, a small number, an eight digit date and a country code, and the stem is written three different lengths in three otherwise identical labels.
- Several blocks carry the group's netname while being registered to a different telecommunications company, so the label and the owner disagree by design.
- Another company's blocks use their own short netname, keeping their identity inside the group's routing.
- Reverse names combine a letter and digit prefix, the full address, a dynamic or static marker, and a three or four letter town code before the group's domain.
- One block's registry lookup failed, so nothing can be said about who holds it.
Interesting
- The town codes make the reverse names a map. Each answer says which exchange the subscriber is on, which is how a support desk triages a fault and also how an outsider infers the network's geography.
- Dates in netnames are provisioning receipts, and the varying stem length shows they are typed rather than generated. Three attempts at the same format produced three different results.
- A group assembled from smaller carriers shows up as exactly this: one netname where the paperwork was updated, the original one where it was not.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,782 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.
