Basic usage is fairly simple - just execute the 'ifconfig' command sans any options. ifconfig. In output, you'll see information related to all active interfaces.
In this example, IPv4 address is 192.168.122.1; Subnet Mask is the value used to calculate network address which is 255.255.255.0 in this case; Default Gateway is the IP address of the network gateway where communication can be done outside of the network. In this example, the default gateway address is 192.168.122.1 linux - How to set the Default gateway - Unix & Linux ifconfig is not the correct command to do that.. You can use route like in route add default gw 192.168.0.254 for example.. And if route is not present, but ip is, you can use it like this: ip route add default via 192.168.0.254 dev eth0, assuming that 192.168.0.254 is the ip of your gateway ifconfig vs ip usage guide on Linux | ComputingForGeeks In all examples, any command with prefix ifconfig is specific to the ifconfig tool and any command starting with ip is specific to the ip network management tool. So keep this in mind as you proceed. Display network interfaces and ip address information. To get all IP address related information using ip/ifconfig, these commands are used. How to use the ip command in favor of the deprecated ifconfig In fact, no work has been done on ifconfig for some time now. In its place is the ip command. Although some aren't exactly happy about this choice, the die was cast and we must move on (sort of).

You can change the MAC address of your interfaces manually using the ifconfig command. A basic example is demonstrated below. First, disable the interface using ifconfig down.

Country lookup. ifconfig Command – Linux Network Management With Examples If we want to set an IP address, netmask and broadcast address in single ifconfig command we will use the following example syntax. $ sudo ifconfig ens3 192.168.122.201 netmask 255.255.255.0 broadcast 192.168.122.255. As we see in the command we provide first interface name and then the IP address. Network Administration: Linux ifcfg Files - dummies
