media business australia

AUSTEREO-AU is held by Austereo Pty Ltd.

What it's used for

  • The space carries the internal network infrastructure for an Australian mass media company, identified by the netname AUSTEREO-AU and registrant Austerio Pty Ltd.
  • The AS announces a single IPv4 prefix, 203.1.208.0/21, comprising 2048 addresses, with one observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, web services, and media production endpoints for the radio broadcasting operations formerly associated with the Today Network and Triple M brands.

Notable

  • The RDAP registrant Austerio Pty Ltd aligns with the AS handle AUSTEREO-AU, confirming the ownership of the address space.
  • Austereo was an Australian mass media company based in Melbourne that operated radio stations under the Today Network and Triple M brands before being acquired and rebranded as Southern Cross Austereo.
  • The address inventory consists of a single contiguous /21 block, typical of a corporate network segment.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
