Obtaining the http clients IP address

[System Mirror Admin]

When request.RemoteAddr is invoked, it returns a 169.254.0.0/16 address. Is there another way to get the clients IP address? Other load balanced environments I've worked with add it as an HTTP header. Does Google do the same?

You can get the client IP from header X-Forwarded-For. Details are here: https://cloud.google.com/appengine/docs/flexible/go/reference/request-headers
