3 ways to find gateway ip in Linux

Table of Contents

 

There are a few different ways that you can check your gateway in Linux. In this blog post, we will discuss three of them. The first way is to use the ip route command. This command displays all of the information about your network interfaces, including the gateway. The second way is to use the route command. This command allows you to view and modify the routing table on your system. The third way is to use the netstat command. This command shows all active network connections and their status. Let’s take a closer look at each of these methods!

Understanding gateway in Linux

A network gateway is a device that connects two networks together. In the context of Linux, a gateway is often used to connect a local network to the Internet. A gateway can be a hardware device, such as a router, or it can be a software program, such as a proxy server. By using a gateway, you can allow computers on your local network to access resources on the Internet.

Find gateway ip with ip route command in Linux

The best way to find the gateway ip in Linux is using ip route command. To use this command, simply type “ip route” into the terminal and press Enter. The gateway is typically listed under the “default” section.

To get the network gateway ip with the ip route command in Linux, follow these steps:

  • Open the terminal.
  • Type “ip route” and press ENTER.
  • The gateway will be displayed next the “default via”.

 

This command will display many information about your network interfaces, including the gateway.

$ ip route
default via 172.31.32.1 dev eth0 proto dhcp metric 100
172.31.32.0/20 dev eth0 proto kernel scope link src 172.31.37.167 metric 100

Check gateway ip with route command in Linux

The route command is another way to view and modify the routing table on your system. To get the gateway, simply type “route -n” into the terminal. This will display all of the routes that are currently configured on your system. U means the route is ‘up’ and the G indicates that it is gateway.

To check the network gateway info with the route command in Linux, follow these steps:

  • Open the terminal.
  • Type “route -n” and press ENTER.
  • The gateway will be displayed under the “Gateway” column.

 

$ route -n
Kernel IP routing table
Destination   Gateway     Genmask     Flags Metric Ref  Use Iface
0.0.0.0     172.31.32.1   0.0.0.0     UG  100  0    0 eth0
172.31.32.0   0.0.0.0     255.255.240.0  U   100  0    0 eth0

If you want to add a new route, you can use the “-add” option. For example, if you wanted to add a route for the 192.168.0.0/24 network, you would type “route add -net 192.168.0.0/24” into the terminal.

Get gateway ip with netstat command in Linux

The netstat command is an another way to view all of the active network connections on your system. To get the network gateway, simply type “netstat -rn” into the terminal.

  • Open the terminal.
  • Type “netstat -rn” and press ENTER.
  • The gateway will be displayed under the “Gateway” column.

 

$ netstat -rn
Kernel IP routing table
Destination   Gateway     Genmask     Flags  MSS Window irtt Iface
0.0.0.0     172.31.32.1   0.0.0.0     UG    0 0     0 eth0
172.31.32.0   0.0.0.0     255.255.240.0  U     0 0     0 eth0

Netstat will display all of the active network connections and their status. If you want to see more information about a specific connection, you can use the “-a” option. For example, if you wanted to see more information about the connection to 192.168.0.0/24, you would type “netstat -a | grep 192.168.0.0/24” into the terminal.

How to change the default gateway in Linux?

The command to change the default gateway in Linux is “route”. For example, to add a new default gateway with the IP address 192.168.0.254, you would use the following command: “route add 192.168.0.254”.

What is the difference between a gateway and a router?

A gateway is a device that connects two networks. A router is a type of gateway that is used to connect two or more computer networks.

What is the difference between a default gateway and a static route?

A default gateway is the network router that your computer uses to connect to the Internet. A static route is a route that has been manually configured by a user.

How to add a static route in Linux?

The command to add a static route in Linux is “route”. For example, to add a new route for the network 192.168.0.0/24 with the gateway 192.168.0.254, you would use the following command: “route add -net 192.168.0.0 netmask 255.255.255.0 dev eth0

How to delete a static route in Linux?

The command to delete a static route in Linux is “route”. For example, to delete the route for the network 192.168.0.0/24 with the gateway 192.168.0.254, you would use the following command: “route del -net 192.168.0.0 netmask 255.255.255.0 dev eth0

How to check Ip address in Linux

The ip command is a great way to view all of the information about your network interfaces. If you want to view more information about your network interfaces, you can use the “ip addr” command. This command displays all of the information about your network interfaces, including the IP address, netmask.

$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 655
36 qdisc noqueue state UNKNOWN group default

The “ip link show” command is great way to view MAC address information about your network interfaces. To view the MAC address info, type “ip link show <interface>” into the terminal.

$ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 0a:4f:94:5e:11:02 brd ff:ff:ff:ff:ff:ff
