Summary

hosting business enterprise
Three adjacent blocks, each half the size of the last, and all three carry the same netname ending in a one.
What it's used for
- A data services company's network. Three IPv4 prefixes announced from the United States, no IPv6, three thousand five hundred and eighty-four addresses, through one observed BGP neighbour.
Notable
- The three blocks sit end to end in one parent range, and each is half the size of the one before it. They could be described in fewer announcements than they are.
- All three share a netname made of the AS handle, three letters for a block, and the numeral one. The numeral is meant to distinguish, and it distinguishes nothing, because there is no second.
- The AS handle is the company's initials with the word for a network attached, so the handle abbreviates four words down to four letters and then adds three more.
- Every block lists the company under its full legal name, comma and corporate suffix included, with no extra contact.
- Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- Blocks that are contiguous and halving usually mean growth granted in instalments: the company came back twice, and each time the registry gave it the next piece rather than a larger one. The shape is a record of how the requests were answered.
- A single upstream carrying everything is a company that buys connectivity rather than routing. The autonomous system exists to hold the addresses, not to choose between paths.

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 2026-10-21, 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 1,779 prefixes, as published 2026-10-22. 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.
