Summary

Hearst Television

United States of America · AI-generated

business media corporate

WJCL-TV is the AS handle for Hearst Television, formerly known as Hearst-Argyle Television.

What it's used for

  • The address space carries corporate infrastructure, 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, a ratio consistent with a small internal corporate estate rather than a transit or access network.

Notable

  • The registrants Hearst Corporation align with the announcer Hearst-Argyle Television, Inc., reflecting the corporate structure of the media conglomerate.
  • The operator was formerly Hearst-Argyle Television, Inc., which was renamed to Hearst Television, Inc. following corporate restructuring within the Hearst Communications family.
  • The inventory consists of two /24 blocks (167.173.48.0/24 and 167.173.240.0/24) with no IPv6 prefixes, indicating a compact IPv4-only footprint.

Reputation

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
