AS13796 — UCONN-ARIN

AS13796 announces 3 IPv4 prefixes covering 90,112 addresses and 0 IPv6 prefixes.

About this network

Ninety thousand addresses from three eras of allocation, all under one netname and one upstream.

What it's used for

• A university's network. 90,112 addresses across three IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The prefixes are 137.99.0.0/16, 50.28.128.0/18 and 67.221.64.0/19, from three different parts of the address space.
• All three are netname UCONN-NET, registered directly to the university.
• One neighbour carries the whole network.
• First seen in the routing archive on 2003-08-19, timestamped in the afternoon.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• A /16 marks an institution present when addresses were handed out freely. A /18 and a /19 from ranges issued much later mark one that kept coming back and was still granted large blocks. Holding all three directly, rather than borrowing from a carrier, is rare at any size.
• One netname across three separate allocations is a registry kept tidy on purpose. Most organisations in this range accumulate a different label per request; this one relabelled everything to match.
• Ninety thousand addresses behind a single upstream is the same trade the other large universities here have made. The AS number exists to hold the space, not to survive a link failing.
