Domain registration options in 2018

[jachin99]

I'm looking to setup a domain on what 2011 but I'm not exactly sure how to make it through the wizard.  I'm sure the windows live domain isn't an option anymore so I have purchased a domain name from GoDaddy.  I don't know how to get that name to resolve to my servers IP address even with port forwarding setup on my router.  I also don't understand the difference between remote web access from the want and seeing up a domain in what 2011.  Any help would be greatly appreciated
