Summary

City of San Diego

United States of America · AI-generated

government municipal network

CITY-OF-SAN-DIEGO is operated by the City of San Diego.

What it's used for

  • The address space is registered under the netname SANNET1 with registrant City of San Diego; DoIT-Networking-DNS, indicating municipal network infrastructure.
  • The AS announces 1536 IPv4 addresses across 3 prefixes and maintains 3 observed neighbours, a ratio consistent with a small, self-contained government network rather than a transit or large-scale access provider.

Notable

  • All registrants in the RDAP data agree with the announcer, listing City of San Diego; DoIT-Networking-DNS for every announced prefix.
  • The address inventory consists of three distinct IPv4 blocks: 156.29.4.0/22, 156.29.3.0/24, and 156.29.64.0/24, all located in the United States.
  • No IPv6 prefixes are announced in the inventory.

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 2026-11-03. 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.
