From there, the request goes to the upstream provider in Rome, Italy, then connects to the ISP in Hamburg, Germany. So your computer starts by checking local DNS cache, then the request is sent to your local Bari ISP.The DNS server settings will be pre-populated with public DNS server IP addresses.You can override the IP address with any other DNS server IP address of your choice.Override External IP: The external IP is usually configured automatically during connection.

As a result, your domain will be resolved to your previous host from the places where the propagation has not been completed yet and to a new one – from the places where it has already passed.
In such a way, you may avoid a downtime as both hosts will show you the same result – your new website.
This assigns a new hostname that can be used to conveniently identify a device within the network, such as an office printer.
