Summary
Symbio Networks
voip wholesale isp australia
SYMBIO-AS-AU-AP is operated by Symbio Networks.
What it's used for
- The address space carries VoIP and DSL access traffic, evidenced by netnames
SYMBIONET,MYNETFONELIMITED-AU, andINABOX-AU, and reverse DNS entries likestatic.qld.dsl.net.au. - With 169,984 IPv4 addresses across 89 prefixes and only 14 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
- As a wholesale VoIP carrier, traffic from this AS consists primarily of voice signalling and media for over 200 service providers, as well as DSL subscriber access.
Notable
- Registrants include Symbio Networks Pty Ltd, My Net Fone Limited, and Telcoinabox Operations Pty Ltd, reflecting the consolidation of multiple brands under the Symbio umbrella.
- Symbio Networks rebranded from MyNetFone, consolidating its enterprise business (MNF Enterprise) and expanding into New Zealand.
- The inventory is a mix of large /17 and /18 blocks alongside numerous smaller /20 and /21 prefixes, all located in Australia.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
