What about localhost
Okay. Yea, that's software that lets you run a web server from your computer. So you'll want to use localhost as its hostname/address, since it's running from your localhost.
What about it? 127.0.0.1 ^That's localhost, if that's what you're asking. Many applications allow you to use 'localhost' rather than having to type out the IP. Was just letting you know the IP for information, and for the instances where you can't call it by name. Hope that helps.
http://127.0.0.1/phpMyAdmin/index.php ^That's how you would access it, if that's what you're asking also. That should take you to the login page for it. If you're trying to install, I think it was another link, but it's been a long time so just reference their website for help.
