Unclassified ARIN
Summary
ALE USA
enterprise business telecom
Three routes for one contiguous run, because the run starts one block above a boundary.
What it's used for
- A communications equipment vendor's network. Three IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- The three blocks are contiguous:
198.206.181.0/24,198.206.182.0/23and198.206.184.0/22sit end to end with no gap between them. - They cannot be announced as fewer routes, because the run begins one block above the alignment a single covering prefix would need. Three is the minimum here, not a mistake.
- All three carry the same netname, prefixed with a type word rather than named for anything, and the same registrant.
- The AS handle is a four-part string: the company initials, a region code, a site code and a counter.
- Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- This is the counter-example to a pattern that shows up constantly in this range. Adjacent blocks announced separately usually means nobody aggregated them. Here the split is forced by arithmetic, and the three sizes are exactly what a minimal covering set looks like for a run of seven blocks starting at an odd offset.
- A four-part handle encodes a location and a role in a field with no schema. It reads as structured data, but nothing validates it, and the expansion of each part exists only in the head of whoever registered it.
- Seventeen hundred addresses behind two upstreams is a corporate network, not a product one.

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 2026-10-27, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
