AS18760 AS18760 - City of Rancho Cucamonga
Unclassified ARIN
Summary
City of Rancho Cucamonga
government municipal network
AS18760 is operated by the City of Rancho Cucamonga.
What it's used for
- The address space carries municipal network infrastructure, evidenced by netnames
RCHCUCAMONGAandRCHCUCAMONGA-2registered to the City of Rancho Cucamonga. - The AS announces 776 IPv4 addresses across 4 prefixes with only 2 observed neighbours, indicating a small, self-contained municipal network rather than a transit or large-scale access provider.
Notable
- Registrants for the two largest prefixes match the announcer, while the smaller prefixes are registered to Level 3 Parent, LLC and CENIC, suggesting leased or historically allocated space.
- The inventory consists of three /24 blocks and one /29 block, with no IPv6 prefixes announced.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
