How do you choose the right SNI masking domain for VLESS Reality to avoid blocking?

CHOOSE A POPULAR FOREIGN RESOURCE WITH TLS 1.3 AND HTTP/2 SUPPORT.

With the Reality protocol, the client sends a third-party domain name to DPI filters to disguise the tunnel as a legitimate site. If the chosen domain is blocked by the provider or lacks modern cipher support, the connection is instantly dropped.

DPI System Requirements for the Target Server

During the TLS handshake check, filters compare the node's response with the specified site's characteristics. If the masking domain uses redirects, runs on slow hosting, or uses outdated TLS 1.2, automation flags the anomaly and blocks traffic based on signature mismatch.

Criteria for Selecting a Reliable Domain

Check TLS 1.3 and HTTP/2 support using online SSL check utilities.
Use domains of major international services or CDNs that are not on blocklists.
Avoid resources with automatic redirects to other addresses (HTTP Redirects).
Match the browser emulation profile (uTLS) to the chosen portal's certificate.
