IP 확인하는 방법

차례

1 ip addr
2 hostname -I
3 ip route

ip addr

ip addr(또는 ip a)을 실행하면 모든 네트워크 인터페이스의 상세 정보가 표시됩니다. IP 주소는 inet 항목에서 확인할 수 있습니다.

# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:00:c8:07 brd ff:ff:ff:ff:ff:ff
    altname enx00155d00c807
    inet 192.168.3.211/22 brd 192.168.3.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fe00:c807/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

grep을 이용하여 IP 주소만 출력할 수 있습니다.

# ip addr | grep "inet "
    inet 127.0.0.1/8 scope host lo
    inet 192.168.3.211/22 brd 192.168.3.255 scope global noprefixroute eth0

hostname -I

# hostname -I
192.168.3.211

ip route

# ip route
default via 192.168.0.1 dev eth0 proto static metric 100
192.168.0.0/22 dev eth0 proto kernel scope link src 192.168.3.211 metric 100
