Summary
Thiel College
education university legacy
THIEL-AS belongs to Thiel College, a small private liberal-arts college in Greenville, Pennsylvania. The network is about as small as a routed AS gets: a single /24 (198.178.162.0/24, 256 addresses) and three observed BGP neighbours.
What it's used for
Campus networking for one college. The /24 is registered in ARIN as THIEL-IP4 directly to Thiel College, so the organisation that announces the space is the organisation that holds it. There is no second-party registrant anywhere in the inventory, which rules out the leased-space and proxy-network shapes that a lone /24 behind a low AS number can otherwise hide.
A campus of Thiel's size needs a public /24 for exactly the things a college puts on the public internet: web and portal front ends, mail, VPN concentrators for staff, and NAT egress for the campus wireless and residence-hall networks. The address count is far too small to be handing public addresses to end users directly.
Notable
Three neighbours against 256 addresses is the signature of a multihomed end site. The AS number exists so the college can hold its own address space and change or add upstreams without renumbering, which for a school is usually driven by moving between a state research-and-education network and a commercial ISP. It is a consumer of transit, never a provider of it.
No PTRs were returned for the two addresses sampled. That is a sample of two, not a finding about the zone, and nothing here is built on it.

Interconnection

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.

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 1,781 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.
