127.0.0.1 automatically redirect to www.127.0.0.1

[marcoman2014]

Hi guys,
i installed last two version of xampp,
both are able to open http://127.0.0.1/dashboard/ but if i try to open a php page in the folder htdocs the browser redirect it from 127.0.0.1 to www.127.0.0.1 and is not able to load the page.
i installed few month ago the same xamp version in another computer and works fine, i'm able to open some test website in the folder htdocs.
My OS is windows 10 64bit, and tested few browser like IE and chrome.
