Summary

Los Angeles County Sheriff's Department

United States of America · AI-generated

government law-enforcement internal

COUNTY-OF-LOS-ANGELES-SHERIFFS-DEPARTMENT is operated by Los Angeles County Sheriff's Department.

What it's used for

  • The address space carries internal departmental traffic, as indicated by the netname LA-SHERIFFS and registrant Los Angeles Sheriff's Department across all four announced prefixes.
  • The AS announces 1024 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio consistent with a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications and systems for the largest sheriff's department in the United States, supporting its nearly 18,000 sworn and professional staff.

Notable

  • All registrants align with the announcer, with Los Angeles Sheriff's Department listed for every prefix.
  • The address inventory consists of four non-contiguous /24 blocks within the 146.233.0.0/16 range, reflecting a segmented internal estate.

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: 451 networks and 1,853 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.
