Summary
Vertel (Vertical Telecoms)
isp enterprise transit legacy
AS9519 (VERTELNET) is held by Vertical Telecoms Pty Ltd, the Sydney-based licensed carrier that trades as Vertel. Vertel builds and operates private, mission-critical wireless and fibre networks — microwave links, carrier-Ethernet and private mobile — for government, utility and enterprise customers rather than for consumers.
What it's used for
The routing shape matches the business exactly. RIS sees 12 IPv4 prefixes covering 6,144 addresses, one IPv6 /36, and 9 observed neighbours. The IPv4 inventory is strikingly regular: almost every prefix is a /23 out of two contiguous ranges (203.82.96.0–203.82.110.0 and 203.188.216.0–203.188.222.0), announced individually rather than as aggregates. That is what deliberate per-service or per-site carving looks like — a carrier handing a discrete block to each managed customer network and traffic-engineering them separately, not an ISP dumping a pool of dynamic subscribers behind one route.
Nine neighbours is the tell for role. It is well above an end-site enterprise (which typically shows one or two) and far below a wholesale transit carrier (hundreds to thousands). It reads as a mid-size carrier with a couple of upstreams and an open peering posture at Australian exchanges, serving a modest number of high-value customers.
Notable
- Vertel is a licensed Australian carrier specialising in mission- and life-critical infrastructure, including networks in fringe-metro, regional and remote locations where fibre alone will not reach.
- The IPv6 allocation is a
/36— far more space than 6,144 IPv4 addresses would suggest, and consistent with a carrier provisioning per-customer v6 delegations. - Address count alone would understate this network. It is a service provider, not an enterprise, despite holding less space than many single corporates.

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: 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.
