DNS Landscape in Vietnam
Vietnam's internet market is dominated by VNPT, Viettel, and FPT. The country has invested heavily in fiber infrastructure, especially in Ho Chi Minh City and Hanoi. DNS peering is limited and ISP DNS can be slow. Many Vietnamese users switch to public DNS for better speed and to access blocked services.
Cloudflare has data center presence in Vietnam, giving it a significant latency advantage. Google DNS is also popular. The performance gap between public DNS and ISP DNS is substantial in Vietnam.
