Unclassified ARIN
Summary
Washoe County
government infrastructure
Eight thousand addresses for a county, in one route, with nothing published.
What it's used for
- A county government's network. A single IPv4
/19announced from the United States, no IPv6, and four observed BGP neighbours.
Notable
- The AS handle, the netname and the registrant all name the same county, with the handle and netname identical.
- The whole allocation is carried as a single route, with no fragmentation into smaller pieces.
- Four upstreams for one block, which is more than most networks this size hold.
- Three addresses were queried for reverse DNS and none returned a name.
- The block sits in space allocated when addresses were issued in large contiguous runs.
Interesting
- County government covers courts, elections, public health, emergency dispatch and libraries, which is why the allocation is the size it is. Each of those was once a separate department with its own addressing, all under one route.
- Four upstreams is the interesting number. Emergency services do not tolerate a single provider failing, and the routing here reflects that rather than any need for capacity.
- Publishing nothing in reverse means the addresses give no hint which range belongs to which department, which for a network carrying dispatch and voter systems is the sensible default.

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 2026-10-20, 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 2026-10-21. 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.
