Summary
Hearst Television
business media corporate
The AS handle KMBC-TV is held by Hearst-Argyle Television, Inc., the broadcasting division of Hearst Communications.
What it's used for
- The address space carries corporate infrastructure for the media conglomerate, evidenced by the netname
HEARSTCORPassociated with both announced prefixes. - The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, indicating a small, self-contained internal corporate estate rather than a transit or access network.
Notable
- The RDAP registrants for both prefixes are listed as Hearst Corporation, which aligns with the announcer's identity as a subsidiary of the parent company.
- The operator was formerly known as Hearst-Argyle Television, Inc., a name resulting from the merger of Hearst Corporation's broadcasting properties and Argyle Television Inc.
- The inventory consists of two /24 blocks, 167.173.19.0/24 and 167.173.211.0/24, with no IPv6 prefixes announced.

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 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
