AS7578Global Secure Layer
As of 23rd October 2026, AS7578 (Global Secure Layer), a network registered in Australia with APNIC, originates 8 IPv4 prefixes covering 3.6k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 19,023rd-largest of the 79,666 networks we see originating IPv4, and the 282nd-largest of 1,669 in Australia. It is seen behind 1 upstream network, most often AS137409 (GSL Networks Pty LTD), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA. 92% of its routes reach at least 90% of full-feed peers.

Upstream graph
The networks AS7578 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS7578 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
