Change dummy domain and show device's hostname in ping

* Change dummy domain
Allows users to access Pi-hole console with my.pi-hole.net instead of the IP address

* Cleaned up formatting

* Put device hostname at the top of the list
Changed my.pi-hole.net to pi.hole and placed it under the device hostname. This way, ping will return the device hostname but you still can access the web interface with pi.hole/admin
