Summary

Hearst-Argyle Television

United States of America · AI-generated

business media corporate

The AS handle WXII-TV is held by Hearst-Argyle Television, Inc., a subsidiary of Hearst Corporation.

What it's used for

  • The address space carries corporate infrastructure for Hearst's television operations, evidenced by the netname HEARSTCORP and registrant Hearst Corporation on both announced prefixes.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.

Notable

  • The registrants for both prefixes are Hearst Corporation, which aligns with the announcer Hearst-Argyle Television, Inc. as a subsidiary of the parent company.
  • Hearst-Argyle Television was taken private by Hearst Corporation in a buyout deal, consolidating the station group under the parent company's direct ownership.
  • The inventory consists of two /24 blocks (167.173.23.0/24 and 167.173.215.0/24), representing a finely subdivided internal network for corporate use.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
