(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 .
queryStrategy controls whether V2Ray queries IPv4, IPv6, or both. If you request both ( UseIP ), but your IPv6 path is broken, the resolver will wait for an IPv6 timeout (~5–10 seconds) before falling back to IPv4.
8.8.8.8 or 8.8.4.4 (Highly reliable infrastructure).
To prevent leaks:
Tap the Slow DNS plugin icon. Enter a public resolver like 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in the DNS field, then paste your unique Name Server and Public Key into their respective boxes. Connect
If your configuration forces V2Ray to query a remote, secure DNS server over an unoptimized proxy tunnel, every single web asset (images, scripts, trackers) must wait for that slow handshake to finish.

The key is to break the loop by creating an exception for your DNS traffic.
Some ISPs rate-limit DNS queries to non-default resolvers, causing artificial delays or TCP fallback.

If V2Ray forwards DNS queries to a server that ultimately routes back through V2Ray (a loop), latency explodes.
To fix a slow DNS server in V2Ray, you must optimize your client or server JSON configuration file. Below is a structured guide to building a high-performance DNS block. 1. Implement a Dual-DNS Strategy
If V2Ray is configured to forward DNS queries through a proxy outbound (e.g., VMess), and that proxy path has high latency or packet loss: Connect If your configuration forces V2Ray to query
