About this network

CSIRO — the network of the Commonwealth Scientific and Industrial Research Organisation, Australia's national science agency and one of the largest government research bodies in the country.

What it's used for

• Connects CSIRO's laboratories, research sites and offices across Australia.
• Announces a large legacy footprint — roughly half a million IPv4 addresses, including 150.229.0.0/16-derived space and several early 192.x and 203.x blocks — plus IPv6 out of 2405:b000::/32.

Notable

• A government research network rather than an ISP: the address space serves CSIRO's own scientists and instruments, not paying subscribers.
• The registry history straddles two RIRs. The ASN sat in ARIN's registry and was moved into APNIC as part of the early-registry (ERX) transfers, so ARIN's copy now simply points at APNIC.

Interesting

• CSIRO is well known outside networking for its role in the research behind wireless LAN patents that underpin modern Wi-Fi.
