STSCI-NET is operated by Space Telescope Science Institute.

What it's used for

  • The address space carries internal network infrastructure for the Space Telescope Science Institute, with netnames STSCI-NET, STSCI-C-NET, and STVIZ-ORG all registered to the same entity.
  • The AS announces 33280 IPv4 addresses across 9 prefixes while maintaining only 3 observed neighbours, indicating a self-contained research network rather than a transit or access provider.

Notable

  • All registrants in the RDAP data agree with the announcer, consistently listing Space Telescope Science Institute as the holder for every prefix.
  • The address inventory is finely subdivided into multiple blocks within the 130.167.0.0/16 range, reflecting site-by-site segmentation typical of a large corporate or institutional estate.
  • The institute serves as the science operations center for the Hubble Space Telescope and the James Webb Space Telescope, managed by AURA for NASA.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, 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 1,783 prefixes, as published 2026-10-17. 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.
