you should make a http request to GET your ip address:
and if that returns your home page with a 200 OK you have a domain canonicalization problem.
in any case the response should probably be a 301 Moved Permanently to your canonical home page url.
unless you have other plans for the url with your ip such as a control panel or site admin interface...
