Internet infrastructure in Thailand
IP addresses allocated to Thailand (TH) are managed by APNIC, the regional internet registry serving Asia. APNIC delegates IP ranges to local registries, ISPs, and large organizations, who in turn assign individual IPs to customers and devices.
When you see an IP geolocated to Thailand, it usually reflects the country its block is registered to — though the actual user could be elsewhere if they're on a VPN, a multinational corporate network, or a cloud provider with regional egress points in Thailand.
Public DNS in Thailand
Most users in Thailand rely on DNS servers provided by their ISP. For better performance and privacy, public DNS servers from Cloudflare, Google, Quad9, and others are usually faster and don't share queries with the local ISP.
Common privacy considerations
Whether you're a resident of Thailand or visiting, the same network fundamentals apply: your public IP reveals approximate location and ISP, your DNS queries can leak outside any VPN tunnel, and modern privacy-focused browsers help limit what websites can fingerprint about you.
Tools to investigate IPs in Thailand
- IP Lookup — enter any IP to see geolocation, ISP, ASN, and timezone.
- WHOIS Lookup — registry-level allocation details for any IP or domain.
- Blacklist Check — verify an IP isn't on common spam lists.
- Hostname Lookup — resolve a .th domain to its IPs and DNS records.
Frequently asked questions
Which regional internet registry allocates IPs in Thailand?
APNIC — the regional internet registry for Asia and the Pacific.
What is the country code top-level domain for Thailand?
Thailand's ccTLD is .th. ccTLDs are reserved for use by entities connected to the country — most domain registrars in Thailand sell second-level domains under it.
How can I find an IP address from Thailand?
Use our IP Lookup tool with any IPv4 or IPv6 address. The tool reports geolocation, ISP, and ASN. IPs allocated to Thailand usually carry registry data showing Thailand as the registered country.
Why does an IP in Thailand sometimes geolocate elsewhere?
IP geolocation is approximate — based on ISP-supplied data and routing observations. CGNAT (where many subscribers share one public IP), VPNs, and corporate networks can place an IP visually far from the user's actual location. Mobile carrier IPs in particular often resolve to the carrier's central data center, not the subscriber.
Are there public DNS servers in Thailand?
Cloudflare (1.1.1.1), Google (8.8.8.8), and Quad9 (9.9.9.9) operate global anycast DNS networks with edge points in or near most countries — including Thailand where coverage permits. Local ISPs in Thailand also operate their own resolvers, which are usually used by default.
