Macでネットワークインターフェイスに割り当てられたIPアドレスを調べる方法

Posted at

MacBookなどでWiFiに接続しつつ、LANケーブルを繋ぎこむとネットワークインターフェイスが複数できる。本稿では、このようなシーンでそれぞれのネットワークインターフェイスに当っているIPアドレスを調べる方法を説明する。

ネットワークハードウェアのリストを出す

networksetupコマンドを使うと、Macのネットワークハードウェアを一覧できる。出力のDeviceの値がifconfigのネットワークインターフェイス名と一致する。

$ networksetup -listallhardwareports

Hardware Port: Thunderbolt Ethernet
Device: en8
Ethernet Address: a8:20:66:24:d4:3f

Hardware Port: Wi-Fi
Device: en0
Ethernet Address: dc:a9:04:78:61:8b

Hardware Port: Bluetooth PAN
Device: en6
Ethernet Address: dc:a9:04:73:dc:65

Hardware Port: Thunderbolt 1
Device: en1
Ethernet Address: aa:00:c9:08:ec:01

Hardware Port: Thunderbolt 2
Device: en2
Ethernet Address: aa:00:c9:08:ec:00

Hardware Port: Thunderbolt 3
Device: en3
Ethernet Address: aa:00:c9:08:ec:05

Hardware Port: Thunderbolt 4
Device: en4
Ethernet Address: aa:00:c9:08:ec:04

Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: aa:00:c9:08:ec:01

ネットワークインターフェイスに割り当てられたIPアドレスを調べる

割り当てられたIPを調べるにはifconfigコマンドを使う。networksetupコマンドで調べたインターフェイス名からIPアドレスを引く。

$ ifconfig en0
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	ether dc:a9:04:78:61:8b
	inet6 fe80::148c:c32:e7bf:9bc%en0 prefixlen 64 secured scopeid 0x8
	inet 172.20.10.4 netmask 0xfffffff0 broadcast 172.20.10.15
	inet6 2001:240:241a:8c30:d2:6945:d5a1:6a33 prefixlen 64 autoconf secured
	inet6 2001:240:241a:8c30:1582:71cf:5eb2:ca6d prefixlen 64 autoconf temporary
	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect
	status: active
$ ifconfig en8
en8: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=10b<RXCSUM,TXCSUM,VLAN_HWTAGGING,AV>
	ether a8:20:66:24:d4:3f
	inet6 fe80::863:126f:5921:7e83%en8 prefixlen 64 secured scopeid 0x12
	inet 192.168.5.67 netmask 0xffffff00 broadcast 192.168.5.255
	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect (1000baseT <full-duplex,flow-control,energy-efficient-ethernet>)
	status: active
