V2ray Slow Dns Server < HD — 1080p >
Update your Linux system's local resolver as well by editing /etc/resolv.conf : nameserver 1.1.1.1 nameserver 8.8.8.8 Use code with caution. Step 4: Fine-Tune Routing to Prevent DNS Loops
to confirm no leaks to your ISP's DNS servers.

DNS resolution might seem instantaneous to most users—but in reality, it's a multistep process that introduces measurable latency. When your browser makes a request, the DNS lookup must complete before any actual data transfer begins. In proxy environments like V2Ray, this latency can be amplified.
This is especially problematic when using public DNS servers located far from your physical location. A DNS server halfway around the world may add 150–300 milliseconds of latency to every single lookup, directly translating to visible loading delays for users. v2ray slow dns server
In the context of V2Ray, the impact of DNS on performance is amplified. V2Ray itself has a built-in DNS server with two main purposes: to resolve a target address for connection and to match routing rules based on the resolved IP of a domain.

Restart V2Ray and monitor the error logs. Look for entries containing failed to lookup , context deadline exceeded , or exchange failed —these indicate DNS resolution problems.
Frequent DNS queries used for data transport can sometimes be flagged by ISP security systems as anomalous behavior, leading to connection resets or temporary throttling. Conclusion Update your Linux system's local resolver as well
V2Ray operates by intercepting outbound traffic, routing it through predefined proxies (VMess, Shadowsocks, Trojan, etc.). Before routing can occur, the target domain name must often be resolved to an IP address. If DNS resolution is slow—whether due to high-latency upstream servers, throttling, or packet loss—the entire proxy pipeline stalls.
