Your default gateway configuration can now be checked by issuing the ip command below. Remember to alter the default gateway address as per your network requirements : You can also configure a default gateway in the following manner. Now in order to check the IP address configuration of enp0s3, proceed as follows:
Remember to modify the IP address and subnet mask according to your needs : The settings configured with the ip command are immediate but they are not persistent since they will be lost after a system reboot.įor temporary IP Address configuration, proceed as follows.

The latter is used to change the logical name of the device whereas the former key(match) relies on some criteria like MAC address, driver…in order to find an adapter. In order to assign a specific logical name to a network interface, you would have to use the match and set-name keys. It is also possible to configure Interface logical names via a netplan configuration. In the snapshot above for instance, we can see only one single Ethernet interface having the logical name of enp0s3 as well as the bus information and all the supported capabilities along with the driver details.
The command l shw yields more details around specific adapters hardware capabilities.
