Summary
Regional Information Sharing Systems (RISS)
government legacy
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 —
199.15.140.0/23,199.15.142.0/24and199.15.143.0/24— are ARIN-registered under the handleRISSNETto Regional Information Sharing Systems. The registrant is the holder, the space is one contiguous199.15.140.0/22worth 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.
RISS2is the inverse case: an opaque, forgettable handle that really does sit on a nationwide law-enforcement network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,778 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
