I dont understand why that would be relevant. If the error message is really for client reading then their brower already is aware of its own IP address and should be able to display that with javascript/Jscript. All modern browsers have that capability. If the error details is for your internal use and not the client, then sending the IP in the body of an error page is the wrong thing to do. A custom header would be better for most uses. X-Client-IP is used already by some software.
