# `--interface`
|
|
|
|
Perform an operation using a specified interface. You can enter interface
|
|
name, IP address or hostname. An example could look like:
|
|
|
|
curl --interface eth0:1 https://www.example.com/
|

On Linux it can be used to specify a **VRF**, but the binary needs to either
|
|
have **CAP_NET_RAW** or to be run as root. More information about Linux
