government municipal california us

CITY-OF-SANTA-CRUZ is operated by the City of Santa Cruz.

What it's used for

  • The address space carries municipal infrastructure, identified by the netname CSC-369 and registrant City of Santa Cruz.
  • The AS announces 256 IPv4 addresses across 1 prefix (207.89.57.0/24) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained government network rather than a transit or access provider.
  • Traffic from this AS consists of internal city services, administrative endpoints, and municipal IT infrastructure for the City of Santa Cruz, California.

Notable

  • The RDAP registrant City of Santa Cruz aligns directly with the AS holder and the registry name.
  • The inventory consists of a single /24 block, representing a compact, dedicated allocation for the municipality.

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 2026-10-24. 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.
