Centos/linux How to view the gateway address/gateway address

Centos/linux How to view the gateway address/gateway address? There are many commands to view the gateway under Linux, but if the IP is obtained by DHCP, then some commands are not applicable, and there are also common query gateway commands.

1.ifconfig-a and cat/etc/resolv.conf (main view ip/netmask and DNS)

2.netstat-rn

3.cat/etc/sysconfig/network

4.cat/etc/sysconfig/network-scripts/ifcfg-eth0

5.traceroute the first line is your own gateway

6.ip Route Show

7.route-n

These are the more common commands for querying gateways. Here's an example:
