If you haven't installed V2Ray yet, you can do so by running the following command (for Ubuntu/CentOS):
Relying on default system DNS instead of the built-in V2Ray DNS routing module. Step-by-Step Fixes for V2Ray Slow DNS
Implementing a split DNS setup where you can route DNS queries through different servers based on the domain can enhance performance and security.
Copy and save the provided Name Server (NS) , Public Key , and the V2Ray VMess/VLESS config . Configure Your VPN App v2ray slow dns server
Tap the V2Ray plugin icon and paste your copied VMess/VLESS configuration.
Use benchmarking tools like DNSBench or Namebench to see how your current DNS servers perform.
V2Ray has a built-in DNS proxy. It intercepts DNS queries (by default, UDP traffic to port 53) and can: If you haven't installed V2Ray yet, you can
When using , a "slow DNS server" usually refers to a bottleneck in the DNS resolution phase , which can make your entire connection feel sluggish even if your actual bandwidth is high. This happens because every website request must first wait for a response from the DNS server before the V2Ray proxy can even start routing data. 🛑 Why V2Ray DNS Can Feel Slow
For real-time applications like online gaming or video conferencing, DNS delays can manifest as jitter and connection instability. Each new connection—such as connecting to a game server or establishing a WebRTC stream—requires DNS resolution, and slow lookups directly impact responsiveness.
Below is an optimized, high-performance dns configuration block. It implements , directing local traffic to fast local servers and restricted traffic to secure, fast remote servers. Configure Your VPN App Tap the V2Ray plugin
To ensure optimal performance and minimize the risk of slow DNS server issues, consider the following best practices:
If DNS traffic is being routed through an overloaded proxy instead of a direct connection for local sites, latency increases.
