Summary
William Rainey Harper College
education infrastructure
A community college holding sixty-five thousand addresses behind one upstream.
What it's used for
- A community college's network. A single IPv4
/16announced from the United States, no IPv6, and one observed BGP neighbour.
Notable
- The block is a
/16, an allocation size now reserved for very large organisations, held by a two year college. - The whole allocation is announced as a single route, with no fragmentation.
- One registry abbreviates the founder's first name with a full stop while the other spells it out, so the same institution is recorded two ways.
- The netname is the surname alone, dropping the two given names the other fields carry.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Allocations like this were made when addresses were free and demand was theoretical. A college that applied early received the same size a corporation would, and nothing since has required it back.
- One upstream is the counterweight. Sixty-five thousand addresses reach the internet through a single connection, so the size of the allocation says nothing about the resilience of the network.
- Announcing it as one route is the considerate choice. The college could split it into hundreds of pieces and every network on the internet would carry them.

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 2026-10-18, 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 1,784 prefixes, as published 2026-10-19. 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.
