Summary

United States of America · AI-generated

utility corporate business infrastructure

APS---ARIZONA-PUBLIC-SERVICE-CORPORATION is operated by Arizona Public Service Company.

What it's used for

  • The address space carries internal corporate infrastructure for a major electric utility, evidenced by the consistent netname APS and registrant Arizona Public Service Company across all announced prefixes.
  • The AS announces 1536 IPv4 addresses across 5 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • All registrants in the RDAP data align perfectly with the announcer, listing Arizona Public Service Company for every prefix.
  • Arizona Public Service is a subsidiary of Pinnacle West Capital Corporation, a publicly traded utility holding company.
  • The inventory consists of five distinct IPv4 blocks within the 137.91.0.0/16 range, with no IPv6 prefixes announced.

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 1,849 prefixes, as published 2026-10-29. 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.
