Summary

Host Networks

Australia · AI-generated

hosting legacy

HOSTNETWORKS-AS-AU-AP belongs to Host Networks, a Brisbane-based Australian hosting company offering colocation, cloud VPS and dedicated servers.

What it's used for

  • Serving customer workloads: colocation, virtual private servers, dedicated hardware and the connectivity around them.
  • Announcing the company's Australian IPv4 space (on the order of 17,000 addresses), a fairly large pool for a regional hosting provider.

Notable

  • This is a hosting network, not an eyeball network: the addresses front servers and customer machines rather than home broadband subscribers.
  • Registered through APNIC with a low AS number from the early 4608-4865 block, which is unusual for an Australian hosting shop of this size.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,851 prefixes, as published 2026-10-29. 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.
