I noticed that gmail.com redirects to mail.google.com, is this because Google bought the domain and redirected it for people who made this assumption or is it because you can assign email addresses to domain names (or something along those lines)?
So by default if you make an email service you have to assign it to a real domain name? Could it be an IP? – 5ives – 2012-11-17T23:03:57.157
According to Wikipedia (see "Email address"), you can use an IPv6-IP, but as you can probably imagine, a regular domain is easier to type. ;) – Peter W. – 2012-11-17T23:07:53.853
It might also be a pure IP address (
xyz@[203.0.113.2]
), but IPv6 surely makes for shorter addresses. You can hardly beatxyz@[::1]
