How do I block all Australia IP addresses?

Download the list above in the format of your firewall: iptables/ipset, nginx, Apache, ufw or MikroTik. Turn on "aggregate" to merge adjacent blocks into fewer rules. The raw list is at /Ranges/AU.txt, one CIDR per line. To inspect a single block use the CIDR calculator.

Who assigns IP addresses in Australia?

APNIC, the regional internet registry for Asia-Pacific. ProxySpace downloads its delegation file every day; the most recent Australia allocation in it is 2026-11-04.
