ifconfig 명령어를 입력하여 IP 정보와 서브넷 마스크, 브로드캐스트등의 다른 정보들도 함께 확인할 수 있습니다.

$ ifconfig
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
	inet 172.16.15.56 netmask 255.255.255.0 broadcast 172.16.15.255
	inet6 fe80::250:56ff:feba:fla8 prefixlen 64 scopeid 0x20<link>
	ether 00:50:56:ba:fl:a8 txqueuelen 1000 (Ethernet)
	RX packets 40901984 bytes 16843183691 (15.6 GiB)

3. ip addr show

ip addr show 명령어를 입력하여 IP 정보와 서브넷 마스크, 브로드캐스트등의 다른 정보들을 함께 확인할 수 있습니다.

$ ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
	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
		valid_lft forever preferred_lft forever
2: ensl60: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
	link/ether 00:50:56:ba:fl:a8 brd ff:ff:ff:ff:ff:ff
	inet 172.16.15.56/24 brd 172.16.15.255 scope global ensl60
		valid_lft forever preferred_lft forever
	inet6 fe80::250:56ff:feba:fla8/64 scope link
		valid_lft forever preferred_lft forever
