Unclassified ARIN
Summary
Tower Hill Insurance Group
finance business
Company initials plus a site code, run together into a word nobody intended.
What it's used for
- An insurance group's network. A single IPv4
/22announced from the United States, no IPv6, and three observed BGP neighbours.
Notable
- The netname joins the company's four initials to a headquarters marker and a counter with no separators, producing a string that reads as an unrelated everyday word.
- The AS handle takes the same four initials and appends a type word instead.
- All three sampled addresses answered, each writing the address into the host label with hyphens.
- Those names carry an extra two-letter label between the host part and the domain, which appears in no other field of the record.
- The routing history begins in 2000.
Interesting
- Concatenating abbreviations without separators is how netnames turn into accidents. Nothing here is wrong, and the result still reads as a word rather than a label, which is a good argument for the hyphen that every other convention in this range uses.
- The extra label in the reverse names is a subdomain doing work: it separates one site's addresses from the rest of the company's namespace. It is the only evidence of internal structure this record contains.
- One thousand addresses behind three upstreams is a company that has decided connectivity matters more than address space, which is the usual shape for an insurer running claims systems.

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 2026-11-02, 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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
