Summary

County of Santa Cruz

United States of America · AI-generated

government municipal california

SCC-44 is operated by the County of Santa Cruz, a local government entity in California.

What it's used for

  • The address space carries municipal network infrastructure, as indicated by the registrant "County of Santa Cruz" and netnames SBCIS990913-81 and CSC-588.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or large access provider.

Notable

  • Both announced prefixes are registered to the "County of Santa Cruz," matching the AS holder and confirming direct ownership of the address space.
  • The inventory consists of two /24 blocks, 63.194.190.0/24 and 216.168.143.0/24, representing a modest internal estate for county operations.

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 1,779 prefixes, as published 2026-10-23. 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.
