"domain": ["full:google.com", "full:youtube.com", "keyword:netflix"]
Setting "domainStrategy": "IPIfNonMatch" ensures V2Ray only resolves IPs when standard domain routing rules fail, preventing unnecessary DNS round-trips. Step 3: Clear OS and Client Cache
To see if DNS queries are leaving your machine as expected:
Split DNS ensures that local websites use fast, local DNS servers, while blocked or proxied websites use secure, remote DNS servers.
: If the connection is unstable, try switching your local DNS resolver to Cloudflare (1.1.1.1) for speed or Google (8.8.8.8) for reliability. Clear Cache v2ray slow dns server
V2Ray has a feature called sniffing . If this isn't configured correctly, the client might wait for a DNS resolution locally before sending the traffic to the proxy. This "double-handling" of the request adds unnecessary milliseconds to every connection. The "Fake DNS" Bottleneck
Use a standard resolver like Google's 8.8.8.8 or 8.8.4.4 .

In conclusion, a "slow DNS server" error or experience in V2Ray is rarely a fault of the protocol itself, but rather a symptom of unoptimized routing. By shifting away from generic settings and toward a localized, encrypted, and intelligently split DNS architecture, users can unlock the true speed of their proxy connections. In the world of advanced networking, the path taken to find a destination is just as important as the speed at which one travels toward it. "domain": ["full:google
Your ISP can see every website you are trying to visit, even if the actual data is encrypted.
Install dnsmasq , unbound , or use systemd-resolved on Linux. Point V2Ray to 127.0.0.1 as its DNS server. The local cache will store resolved IPs, eliminating external lookups for repeated requests.
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.
Many users test their proxies by going to a "DNS Leak Test" website. Clear Cache V2Ray has a feature called sniffing
Run tcpdump -i any port 53 while browsing. Observe:
Using default DNS like 8.8.8.8 from a country far away (or blocked/throttled by ISPs) adds 150–300ms per query.
One bizarre cause of "slow DNS" in V2Ray is .
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.
Editing the basic configuration file is only the first step. To achieve the fastest possible load times, implement these advanced architectural tweaks. Switch to DNS-over-HTTPS (DoH)
