How does a network interface card work?
A network interface card (NIC) is a hardware component without which a computer cannot be connected over a network. It is a circuit board installed in a computer that provides a dedicated network connection to the computer. It is also called network interface controller, network adapter or LAN adapter.
How do I know my interface?
Identify Network Interfaces on Linux
- IPv4. You can get a list of the network interfaces and IPv4 addresses on your server by running the following command: /sbin/ip -4 -o a | cut -d ' ' -f 2,7 | cut -d '/' -f 1. ...
- IPv6. For IPv6, you can run a similar command but use “-6” in place of “-4”: /sbin/ip -6 -o a | cut -d ' ' -f 2,7 | cut -d '/' -f 1. ...
- Full output.
How do I find my default interface?
The Iface column in the line with destination default tells you which interface is used. Get the default network interface typically used to route to the "remaining" internet in opposite to DMZ, private network, VM host etc. which are usually routed explicitly.
