AS15304 — WASHOE-NET

AS15304 announces 1 IPv4 prefixes covering 8,192 addresses and 0 IPv6 prefixes.

About this network

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 /19 announced 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.
