AS9507 NEXTHOP-AS-AP NextHop Pty Ltd

AS9507 (NEXTHOP-AS-AP) is held by NextHop Pty Ltd, an Australian telecommunications carrier based in Sydney. NextHop sells dark fibre, IP transit and high-capacity internet access over its own build, so this is a wholesale carrier network rather than a consumer ISP.

What it's used for

The evidence points squarely at transit. AS9507 announces just 9 IPv4 prefixes — about 4,352 addresses in total — plus three IPv6 /48s from 2405:e480::/32. That is a very small inventory. Yet the AS is observed with roughly 91 BGP neighbours. A network with only a few thousand addresses and ninety-odd peers is not serving its own users; it is carrying other networks' traffic. The address count reflects infrastructure and customer allocations, while the value of the AS sits in the interconnections and the fibre underneath it.

The prefixes themselves are consistent with an Australian carrier that has grown by picking up allocations over time: a 180.222.192.0/22 alongside a scatter of /23s and /24s from APNIC's 103.0.0.0/8 range. Sampled reverse DNS shows a router interface named et0-0-41-341.fi02.syd02.nexthop.net.au — an Ethernet interface on a Sydney facility, exactly the naming a carrier uses for its own backbone gear — and a separate hostname belonging to an Australian business customer riding the same space.

Notable

• NextHop is a facilities-based operator: it builds and lights its own fibre rather than reselling.
• The high neighbour-to-address ratio is the clearest single signal here that this is wholesale transit, not access.
