saw a video where it said all domains have a dot at the end. so it is <http://superuser.com./> this does not work but <https://www.google.co.in./> and <http://sel2in.com>. do work

though for google need to trust the cert as the name does not match

question : what is the format to include port to this scheme? <https://www.google.co.in.:443/> works but not ritemail.blogspot.in.:80/2013/07/funny-lol-pics.html or sel2in.com.:80/g.html

Can someone explain?
