How many IP addresses does Brunei have?
Brunei holds 216,576 IPv4 addresses in 38 blocks and 11 IPv6 prefixes, the 140th largest IPv4 holding of 239 countries (under 0.01% of all allocated IPv4). Compare it with other countries on the IP ranges by country page.
Which networks use the most Brunei IP addresses?
Brunei Shell Petroleum Company Sdn Bhd (AS133875, 65.5K addresses), Unified National Networks (AS10094, 52.5K addresses) and WoodsDale Ventures INC (AS55547, 11.3K addresses). Look up any single address with the IP lookup tool.
How do I block all Brunei 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/BN.txt, one CIDR per line. To inspect a single block use the CIDR calculator.
Who assigns IP addresses in Brunei?
APNIC, the regional internet registry for Asia-Pacific. ProxySpace downloads its delegation file every day; the most recent Brunei allocation in it is 2026-10-09.
Are there free proxies in Brunei?
Not in the current lists. They change every 20 minutes; the proxies by country page shows which countries have proxies right now.
