Find public China Unicom DNS server IP addresses and locations by province and city to optimize your network settings.
No data available. Please configure DNS IP data in tool settings.
When you need to improve browsing speed or resolve DNS issues in a specific region, finding the right China Unicom DNS server IP manually can be time-consuming. This tool lists public China Unicom DNS server IP addresses deployed across China, along with precise city-level location data. Each record includes the starting IP, ending IP, and service location, helping IT professionals quickly identify the most suitable DNS server.
Some IPs may change as networks are adjusted. If DNS resolution fails, try another IP in the same region. Back up your original DNS settings before making changes; enterprise users should test changes on their internal network first.
For latency-sensitive applications such as video conferencing, test response times for 3-5 DNS servers in your region. Example: Beijing users can try 202.106.0.20, 202.106.46.151, or any IP in the 202.106.196.212-217 range.
