Thailand IP ranges: questions

How many IP addresses does Thailand have?

Thailand holds 8,931,328 IPv4 addresses in 1,199 blocks and 241 IPv6 prefixes, the 43rd largest IPv4 holding of 239 countries (0.24% of all allocated IPv4). Compare it with other countries on the IP ranges by country page.

Which networks use the most Thailand IP addresses?

TRUE INTERNET CORPORATION CO. LTD. (AS17552, 1.4M addresses), TOT Public Company Limited (AS23969, 1.2M addresses) and ADVANCED WIRELESS NETWORK COMPANY LIMITED (AS45758, 686.3K addresses). Look up any single address with the IP lookup tool.

How do I block all Thailand 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/TH.txt, one CIDR per line. To inspect a single block use the CIDR calculator.

Who assigns IP addresses in Thailand?

APNIC, the regional internet registry for Asia-Pacific. ProxySpace downloads its delegation file every day; the most recent Thailand allocation in it is 2026-10-26.

Are there free proxies in Thailand?

Yes, 405 in the current lists. See free Thailand proxies for the lists per protocol, refreshed every 20 minutes.
