What is Default Gateway? How to Find the Default Gateway?

Knowing your default gateway IP address is useful to troubleshoot the home or business network successfully.

It is also useful to gain access to the router’s web-based interface. The default gateway IP address is used to communicate with your local home network.

What is a default gateway address?

The default gateway address is a node or router that acts as an access point to transmit network traffic from the local network to the remote network or internet.

Simply put, the default gateway acts as a middleman or intermediary between your local network and the internet.

It works to take the information from the local network or home network and transmit it to the internet or vice versa.

A local network, also called a home network or business network, usually contains a single router, and multiple devices are connected to that router.

The IP address assigned to the router is called a private IP address or local IP address, or default gateway.

The term “default gateway” is used in Windows operating system. In iOS and Mac devices, it is termed as “router.

Moreover, in Linux based operating system, it is named as “gateway” or “gateway route.

What is the purpose of the default gateway?

The default gateway determines the path that is needed to connect the local network to remote network segments.

It acts as an exit point for all the data packets leaving the local network to reach the destination server.

Moreover, you need to understand that router’s default gateway has the same subnet mask as your computer or devices in a network.

However, if you don’t provide a gateway address, your device cannot communicate with another network outside your local network.

In other words, your data packets cannot reach other networks.

Here, we will look into finding your default gateway IP address on Windows, Mac OS, iPhone/iPad iOS, Android, and Linux operating systems.

How to find default gateway in Linux

There are many ways you can find the default gateway in Linux. The most common is through the “IP route” command, “route” command, and “netstat” command in Linux operating system.

Using route command to find the default gateway

You have to type the command.”route -n” in your terminal. And, the below output will show that the default gateway is 192.168.1.1. Here, UG indicates network link, where “U” stands for Up and “G” for Gateway.

[email protected]:~$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth1
192.168.1.0     0.0.0.0         255.255.255.0   U     1      0        0 eth1

Using IP route command to find the default gateway

You have to type in the “IP route show” command and then look for “default” to get the default gateway.

[email protected]:~$ ip route show
default via 192.168.1.1 dev eth1  proto static 
192.168.1.0/24 dev eth1  proto kernel  scope link  src 192.168.1.100  metric 1

Using netstat command to get the default gateway

In the terminal, you have to type in.”netstat -rn” for the default gateway.

[email protected]:~$ netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
0.0.0.0         192.168.1.1     0.0.0.0         UG        0 0          0 eth1
192.168.1.0     0.0.0.0         255.255.255.0   U         0 0          0 eth1

In the above result, you will see that it is using “eth” configuration files.

If your network interface uses “eth0” configuration files, you have to use different Linux systems’ commands.

In RHEL (Red Hat Enterprises Linux) based systems, you have to type.”cat /etc/sysconfig/network-scripts/ifcfg-eth0” and then look for “Gateway” to get the default gateway or local IP address.

[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="yes"
ONBOOT=yes
TYPE="Ethernet"
UUID="bcb0a409-d7d4-4f2f-882f-ec46e07e670d"
HWADDR=08:00:27:A6:0C:AC
IPADDR=192.168.1.200
PREFIX=24
GATEWAY=192.168.1.1
DNS1=8.8.8.8
DNS2=192.168.1.200
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"

In a Debian-based Linux system, you have to use the following command.”cat /etc/network/interfaces” and then look for the gateway section for the default gateway IP address.

[email protected]:~$ cat /etc/network/interfaces 
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static

netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Conclusion

The default gateway IP address doesn’t change unless you have manually changed your default gateway IP address or directly connected it to the modem.

If you can’t find your default gateway for the router, refer router manual or look into your router device’s back.

There you will also find your default wireless network name and password.
