I am looking for DNS with IP for remote the office computer by IPAD with port 8443.

You can use Remote Desktop client on your iPad to connect to your office computer which is available at https://itunes.apple.com/us/app/microsoft-remote-desktop/id714464092?mt=8

Signup for a free hostname and run the Dynu IP Update Client software on your office computer so that you can access it using the hostname. Here is a link to a tutorial to setup Remote Desktop:

Not all routers respond to ping imcp packets. You should be able to enable the ICMP protocol in your router to accept ping requests. Please note that ping is not required for the hostname to resolve to an IP address (DNS).

aviation.dynu.net currently points to IP address 128.234.12.131. Please let us know if this is not the correct IP address. Port 3389 (Remote Desktop port) and port 8443 are not reachable on 128.234.12.131. Could you please send your port forwarding settings so that we can confirm if it has been setup properly>
