Summary
PIP (Preferred Internet Provider)
isp business hosting legacy
AS9544 (PIP-AS-AP) is held by Clarenston Pty Ltd, trading as Preferred Internet Provider (PIP), a Sydney-based internet and managed-IT provider. The registry name looks opaque, but the reverse DNS settles it immediately: the space resolves under pip.com.au, and the company today sells business-grade NBN and fibre connectivity, managed IT, private cloud and Microsoft 365 services to Australian organisations.
What it's used for
This is a small independent ISP, and the evidence is unusually legible. RIS sees 8 IPv4 prefixes — every one a /24, 2,048 addresses in total — and no IPv6. The blocks all come from Australia's legacy 203.x ranges (203.23.120.0/24, 203.24.52.0/24, 203.27.90.0/24, 203.34.24.0/24 and neighbours), the sort of space allocated to Australian providers well before the region tightened up.
The reverse DNS shows the network doing exactly what an ISP does. There are infrastructure names (peer-gw.pip.com.au, clients-router5.pip.com.au, pip2.pip.com.au), and there are subscriber-facing ones — adslh-203.23.120.133.pip.com.au and adslb-static-203-24-52-133.pip.com.au are ADSL customer addresses, including static assignments. Alongside those, some addresses carry customer-branded PTRs like armsgroup.com.au and nc.topthis.com.au, which is what hosted or dedicated business customers look like.
Nine BGP neighbours on 2,048 addresses is a respectable amount of interconnection for a network this size, and reflects an ISP that peers to keep its transit bill down.
Notable
- The ADSL-era reverse DNS is still in place even though the business has moved on to NBN and fibre.
- No IPv6 is announced.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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.
