Summary

County of Ventura

United States of America · AI-generated

government municipal california public

The AS handle VENTURACOUNTY is operated by the County of Ventura.

What it's used for

  • The address space is registered under the netname VENTURACTYCA with the registrant listed as County of Ventura, indicating a municipal government network.
  • The AS announces 1536 IPv4 addresses across 6 prefixes and maintains 2 observed neighbours, a ratio consistent with a small-scale internal or site-specific government network rather than a transit provider.

Notable

  • All six announced prefixes share the same registrant, County of Ventura, and netname, VENTURACTYCA, confirming a unified administrative domain.
  • The inventory consists of six /24 blocks within the 157.145.0.0/16 range, representing a modest and contiguous address estate for a county-level entity.

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 1,851 prefixes, as published 2026-11-04. 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.
