AS11096 FLORIDANET

FLORIDANET is a Florida research-and-education network, registered with ARIN to org handle FLORID-23 at Networking Services, 1772 Stadium Road, University of Florida, Gainesville. Its core routers answer under flrnet.org — Florida LambdaRail, the state's R&E backbone — and the space it announces belongs to Florida universities and colleges.

What it's used for

Connectivity for Florida's higher-education institutions. The AS announces 34 IPv4 prefixes (~9,728 addresses) and 3 IPv6 prefixes including a 2607:f5d8::/32, and RIS observes 72 neighbours. That neighbour count against a modest address count is the giveaway: an enterprise of this size would peer with a handful. Seventy-plus adjacencies means the AS is aggregating — carrying member campuses and exchanging routes at exchange points on their behalf, which is exactly what a state R&E network does.

Notable

The prefix registrations name the members directly rather than the operator. 131.91.252.0/22 and 131.91.183.0/24 are registered to FAU (Florida Atlantic University), 169.139.190.0/23 to Eastern Florida State College, and the 108.59.x and 64.56.x blocks to FLR-NET and NET-FLR-PENSC-1. The reverse DNS confirms it — naboo.fau.edu, s183n133.fau.edu, bccnews.brevard.cc.fl.us, and the backbone's own i1-flrcore-108-59-29-133.rtr.net.flrnet.org.

Interesting

This is the benign version of the pattern that flags an address broker: many prefixes registered to parties other than the announcing AS. The difference is that every registrant here is a real, findable Florida institution whose own domain shows up in the reverse DNS. Registrants that are not the holder are only suspicious when the registrants themselves cannot be found.
