Unclassified ARIN
Summary
Hanover College
education business infrastructure
One block, one upstream, one netname that begins with the registry's own word for a block of addresses.
What it's used for
- A college's network. One IPv4 prefix announced from the United States, no IPv6, two thousand and forty-eight addresses, through one observed BGP neighbour.
Notable
- The netname is the registry's abbreviation for a network block, a hyphen, and the college's name. The first half describes the field it is written in.
- The AS handle is the college's full name, both words, hyphenated and in capitals.
- The registrant is the college again, written normally. Three fields, one name, three levels of shouting.
- The whole holding is a single contiguous block, and nothing in the record belongs to anybody else.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A prefix meaning block of addresses on a field whose entire purpose is to name a block of addresses is a fossil from paper forms, when the same sheet held several kinds of record and the prefix said which kind this was.
- Two thousand addresses is a college that registered its space when a college could ask for that much and receive it. The size is a date stamp of a kind, readable without any date in the record.
- One upstream for a campus is the arrangement of an institution that treats connectivity as a utility bill. When it fails, the answer is to wait, and that has been an acceptable answer for a long time.

Reputation
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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
