Summary
Centra Networks
isp legacy
CENTRANETWORKS-AU is an Australian technology services provider operating in Queensland, with offices in Brisbane, Bundaberg, and Hervey Bay.
What it's used for
- Internet connectivity, managed IT, VoIP, cloud, and security services for small and medium businesses in regional Queensland.
- A small routed footprint: a handful of IPv4 prefixes plus IPv6, delivered through Australian upstreams.
Notable
- A regional managed service provider rather than a mass-market ISP, so the address space is dominated by business customers and hosted services rather than residential subscribers.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
