The AS handle ends in a hyphen with the country code missing from behind it.
What it's used for
- A city provider's network. Four IPv4 prefixes announced from Ukraine, no IPv6, four thousand three hundred and fifty-two addresses, across two observed BGP neighbours.
Notable
- The handle is three letters and a trailing hyphen. The holder string carries the same three letters followed by the country code; the handle lost it.
- The four blocks use three netname conventions: two share one form combining the abbreviation, the country code and a network suffix, one drops a letter from the abbreviation, and one uses two letters that appear in neither the company name nor the handle.
- All four list the same company and an abuse role, so the naming varies while the ownership does not.
- The blocks come from four unrelated ranges, the largest a
/21. - The routing archive first saw this number years after the numbers around it, so it was assigned long after its neighbours in the sequence.
- Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- A truncated handle usually means a field with a length limit that nobody checked after saving. It is cosmetic until something tries to match the handle against the holder name, which no longer agrees.
- Three netname conventions across four blocks, with one identical registrant on all of them, is the registry's most common shape: the ownership fields get maintained and the naming fields never do.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
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.
