AS11826 RISS2

RISS2 is the Regional Information Sharing Systems, the US criminal-justice information

sharing program administered through the Department of Justice's Office of Justice Programs

and funded by the Bureau of Justice Assistance. RISS operates RISSNET, the secure network

that links thousands of local, state, federal and tribal law-enforcement agencies for

intelligence sharing, investigative support and event deconfliction. ARIN lists the org in

Nashville, Tennessee, with the ASN registered in January 1999.

What it's used for

• The public-internet edge of RISSNET. RISS is not an ISP, a campus or a business network: it is a federally funded program whose entire purpose is to run a restricted-access system for police and prosecutors, and this AS is how that system is reachable and how its member agencies reach it.
• RIS sees 3 IPv4 prefixes / 1,024 addresses, no IPv6, and 2 observed neighbours. A thousand addresses behind two upstreams is a small, single-purpose government network — the redundancy of two providers, none of the scale of an operator.

Notable

• All three prefixes — 199.15.140.0/23, 199.15.142.0/24 and 199.15.143.0/24 — are ARIN-registered under the handle RISSNET to Regional Information Sharing Systems. The registrant is the holder, the space is one contiguous 199.15.140.0/22 worth of addressing split into three announcements, and nothing third-party appears anywhere.
• No reverse DNS was observed on the six addresses sampled. That is a sample of six out of a thousand and supports no conclusion about the zone.

Interesting

• This range is full of official-sounding handles that turn out to belong to credit unions and trucking companies. RISS2 is the inverse case: an opaque, forgettable handle that really does sit on a nationwide law-enforcement network.
