Internet infrastructure in South Korea
IP addresses allocated to South Korea (KR) 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 South Korea, 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 South Korea.
Public DNS in South Korea
Most users in South Korea 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 South Korea 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 South Korea
- 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 .kr domain to its IPs and DNS records.
Frequently asked questions
Which regional internet registry allocates IPs in South Korea?
APNIC — the regional internet registry for Asia and the Pacific.
What is the country code top-level domain for South Korea?
South Korea's ccTLD is .kr. ccTLDs are reserved for use by entities connected to the country — most domain registrars in South Korea sell second-level domains under it.
How can I find an IP address from South Korea?
Use our IP Lookup tool with any IPv4 or IPv6 address. The tool reports geolocation, ISP, and ASN. IPs allocated to South Korea usually carry registry data showing South Korea as the registered country.
Why does an IP in South Korea 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 South Korea?
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 South Korea where coverage permits. Local ISPs in South Korea also operate their own resolvers, which are usually used by default.
