Summary

Salk Institute

United States of America · AI-generated

research education business

The AS handle SALK-AS is held by Salk Institute.

What it's used for

  • The address space carries institutional infrastructure, evidenced by netnames like SALKNET198 and SALKNET registered to "Salk Institute; Network Operations".
  • The inventory consists of 7 IPv4 prefixes totaling 2304 addresses, with a single observed neighbour, indicating a small, self-contained research network rather than a transit or access provider.

Notable

  • Registrants are predominantly consistent with the announcer, with "Salk Institute; Network Operations" holding most prefixes, though 153.105.81.0/24 is registered to "Dimension Systems" and 198.202.65.0/24 to "San Diego Supercomputer Center".
  • The address inventory is a mix of /23 and /24 blocks, including a legacy /24 from the San Diego Supercomputer Center, reflecting the institute's long-standing presence in the San Diego research community.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
