Summary
Sanford Underground Research Facility
research science underground us
SANFORD-LAB is the autonomous system for Sanford Underground Research Facility.
What it's used for
- The space carries infrastructure for the Sanford Underground Laboratory, with netnames
SDSMTNETandSANFORD-UNDERGROUND-LABORATORY-AT-HOMESTAKEindicating ties to the South Dakota School of Mines & Technology and the laboratory itself. - The AS announces 6144 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a dedicated research network rather than a transit provider.
Notable
- Registrants align with the announcer, listing South Dakota School of Mines & Technology for the 151.159.224.0/20 block and Sanford Underground Laboratory at Homestake for the 204.114.24.0/21 block.
- The facility was established after the Homestake mine closed in 2003, with the property donated to South Dakota in 2006 and funded by T. Denny Sanford and the state to support deep underground science.
- The address inventory consists of two distinct IPv4 blocks, one associated with the university and one with the laboratory, reflecting the collaborative nature of the site.

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 2026-11-05, 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
