Summary

isp telecom infrastructure
The netname says anycast and the routing shows one neighbour, which is anycast with nowhere to cast to.
What it's used for
- A Canadian access provider. 512 addresses in a single IPv4 prefix, one IPv6 prefix, and one observed BGP neighbour.
Notable
- The block is
204.239.130.0/23, netnameUNISERVE-ANYCAST, registered toOkanagan Internet Junction. - The AS handle is
UNISERVE-AS13937, the company name followed by its own AS number. - The IPv6 prefix is
2605:1000:a::/47.
Interesting
- Announcing the same addresses from several places is what anycast means, and it needs several places to announce from. One upstream gives one path, so the netname records an intention, a past arrangement, or a plan that the routing table has yet to catch up with.
- The registrant is a different company from the one the AS is named for, which is the ordinary aftermath of a regional provider absorbing a smaller one. The addresses keep the older name because changing a registry record achieves nothing operationally.
- Putting the AS number in the handle is redundant and useful. The handle already identifies the network, but a human reading a routing table sees the same string twice and needs no second lookup to confirm it.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
