Improve detection of non-public sites for registration

Setup

Local site address

1. Edit your computer's "/etc/hosts" file and assign your local IP address with a hostname with a fully qualified domain name. For example if your local IP address is "192.168.1.10":

   192.168.1.10 tester.in.moodle.com

   Note: You'll need to edit it in privileged mode (e.g. if using xed, "sudo xed /etc/hosts")

Public site address
