V2ray Slow Dns Server May 2026

Option A – Local recursive resolver (Best for latency) Install dnscrypt-proxy, unbound, or systemd-resolved on the same machine as V2Ray, then point V2Ray to 127.0.0.1:53.

Option B – Use Cloudflare Gateway or Quad9 DoH Configure V2Ray to use DNS over HTTPS (no UDP throttling):

"dns": 
  "servers": [
    "https://1.1.1.1/dns-query",
    "https://dns.quad9.net/dns-query"
  ]

Option C – Multi-server with fallback

"dns": 
  "servers": [
    "1.1.1.1",           // primary, fast
    "8.8.8.8",           // backup
    "223.5.5.5"          // local ISP (if trusted)
  ]

If V2Ray forwards DNS queries to a server that ultimately routes back through V2Ray (a loop), latency explodes.

For advanced users using V2Ray with routing (routing object), you can enable Fake DNS. This is the ultimate speed hack. v2ray slow dns server

Instead of waiting for a DNS resolution, V2Ray immediately returns a fake IP (e.g., 223.5.5.5 range) to the client. It maps the fake IP to the real domain internally.

Configuration:

"dns": 
  "hosts": 
    "domain:google.com": "223.5.5.5"
  ,
  "fakeDns": 
    "ipPool": "198.18.0.0/15"

Warning: Fake DNS breaks sniffing on the local client. Only use this on the server side with xray (the V2Ray fork) for VLESS or Trojan protocols.
