mac查IP地址

方法一：

ifconfig

console输出：

zzz@MacBook-Air ~ % ifconfig

	nd6 options=201<PERFORMNUD,DAD>

输出信息太多，可查看硬件端口名，输入如下命令

networksetup -listallhandwareports

Console输出：

zzz@MacBook-Air ~ % networksetup -listallhardwareports

Hardware Port: Wi-Fi
Device: en0
Ethernet Address: 94:f6:d6:21:cb:24

Hardware Port: Bluetooth PAN
Device: en2
Ethernet Address: 94:f6:d6:21:cb:25

Hardware Port: Thunderbolt 1
Device: en1
Ethernet Address: 82:18:60:9a:8c:00

Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: 82:18:60:9a:8c:00

VLAN Configurations
===================

我们只需要查看WiFi端口，即en0

ifconfig en0

@MacBook-Air ~ % ifconfig en0                      
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=400<CHANNEL_IO>
	ether 94:f6:d6:21:cb:24 
	inet6 fe80::1a:2115:3060:33da%en0 prefixlen 64 secured scopeid 0x4 
	inet 192.168.xx.xx netmask 0xffffff00 broadcast 192.168.xx.xxx
	inet6 2409:8900:7e40:3d0f:1802:bd69:49a6:73b6 prefixlen 64 autoconf secured 
	inet6 2409:8900:7e40:3d0f:b1ac:47a0:63d5:6780 prefixlen 64 autoconf temporary 
	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect
	status: active

inet后的IP地址即为自己电脑的本地IP，此处用xx代替数字。
也可以用另一种：

ifconfig | grep "inet"

zzz@MacBook-Air ~ % ifconfig | grep "inet"   
         
	inet 127.0.0.1 netmask 0xff000000 
	inet6 ::1 prefixlen 128 
	inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 
	inet6 fe80::1a:2115:3060:33da%en0 prefixlen 64 secured scopeid 0x4 
	inet 192.168.xx.xx netmask 0xffffff00 broadcast 192.168.xx.255
	inet6 2409:8900:7e40:3d0f:1802:bd69:49a6:73b6 prefixlen 64 autoconf secured 
	inet6 2409:8900:7e40:3d0f:b1ac:47a0:63d5:6780 prefixlen 64 autoconf temporary 
	inet6 fe80::b4fd:66ff:fe22:eaca%awdl0 prefixlen 64 scopeid 0x8 
	inet6 fe80::b4fd:66ff:fe22:eaca%llw0 prefixlen 64 scopeid 0x9 
	inet6 fe80::74c0:5dc8:9a74:d40b%utun0 prefixlen 64 scopeid 0xa 
	inet6 fe80::c77a:cdc5:7c98:f4b9%utun1 prefixlen 64 scopeid 0xb 

方法二：

nslookup localhost

zzz@MacBook-Air ~ % nslookup localhost
Server:		2409:8900:7e40:3d0f::9f
Address:	2409:8900:7e40:3d0f::9f#53

Name:	localhost
Address: 127.0.0.1

截止2021年3月mac使用nslookup去查localhost命令无法直接显示ip地址。
但可以查看直接的网址ip：

zzz@MacBook-Air ~ % nslookup www.baidu.com
Server:		2409:8900:7e40:3d0f::9f
Address:	2409:8900:7e40:3d0f::9f#53

Non-authoritative answer:
Name:	www.baidu.com
Address: 39.156.66.14
Name:	www.baidu.com
Address: 39.156.66.18

在浏览器输入网址39.156.66.18可以在跳转到百度页面。

总结：

#查看本地ip
ifconfig
ifconfig en0
ifconfig | grep "inet"
nslookup localhost
#查看所有硬件端口号
networksetup -listallhandwareports
