Summary

ABS-CBN

Philippines · AI-generated

media broadcast corporate

ABS-CBN-PH is operated by ABS-CBN Broadcasting Corporation.

What it's used for

  • The address space carries corporate infrastructure for a major Philippine media conglomerate, as indicated by the netname ABS-CBN-PH and registrant ABS-CBN BROADCASTING CORPORATION.
  • The AS announces a single IPv4 prefix, 221.121.184.0/21, comprising 2048 addresses, with 0 IPv6 prefixes.
  • With only 2 observed neighbours, the network functions as a small, self-contained corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant ABS-CBN BROADCASTING CORPORATION aligns directly with the AS handle and the known identity of the operator.
  • The inventory consists of a single contiguous /21 block, reflecting a compact internal network design typical of a corporate headquarters or primary facility.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
