Summary
Pittsburgh Supercomputing Center (PSC)
education research legacy
The network of the Pittsburgh Supercomputing Center (PSCNET-HS-AS), a high-performance computing and networking center in Pittsburgh, Pennsylvania.
What it's used for
- Connecting PSC's supercomputing resources and research collaborators.
Notable
- A research computing network, not a commercial ISP. Registered in 1991, its low AS number reflects an early-internet allocation.
Interesting
- PSC was founded in 1986 as one of the original five NSF supercomputing centers, a joint effort of Carnegie Mellon University and the University of Pittsburgh. See also its test network AS1207.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
