Package dev.demeng.sentinel.client.util

Class PublicIp

java.lang.Object

dev.demeng.sentinel.client.util.PublicIp

public final class PublicIp
extends Object

Resolves the public IP address of the current machine by querying an external service.

This is useful as a workaround when the Sentinel server sits behind a reverse proxy that does not forward the real client IP (e.g. missing X-Forwarded-For headers). The resolved address can be passed to ValidationRequest.Builder.ip(String) so that Sentinel sees the correct IP regardless of proxy configuration.

 ValidationRequest request = ValidationRequest.builder()
     .product("my-product")
     .ip(PublicIp.resolve())
     .build();
