Summary
WHDH-TV (Sunbeam Television)
enterprise legacy
WHDH-BOS — WHDH, channel 7 in Boston, Massachusetts. The station is owned by Sunbeam Television and operates as the independent, news-heavy "7NEWS".
What it's used for
- Broadcaster corporate and newsroom networking: a single
/24(256 addresses), which is about what a station needs for its own infrastructure.
Notable
- An eyeball-facing brand, but not an eyeball network — this is a media company's own enterprise AS, not consumer access.
- Despite the low number, the ASN was registered to WHDH-TV only in 2014, so AS4505 is a reissued number rather than an early-internet allocation.
Interesting
- WHDH was Boston's CBS affiliate, then NBC's from 1995, and became an independent station on 1 January 2017 after NBC moved to its own O&O.

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 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
