About this network

A community college holding sixty-five thousand addresses behind one upstream.

What it's used for

• A community college's network. A single IPv4 /16 announced 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.
