Virtual network interface in Mac OS X

Question

I know that you can make a virtual network interface in Windows (see here), and in Linux it is also pretty easy with ip-aliases, but does something similar exist for Mac OS

Answer 1

A few others seemed to hint at this, but the following demonstrates using ifconfig to create a vlan and test DNS on the virtual interface (using minidns) on OS X 10.9.5:

$ sw_vers -productVersion
10.9.5
$ sudo ifconfig vlan169 create && echo vlan169 created
vlan169 created
$ sudo ifconfig vlan169 inet 169.254.169.254 netmask 255.255.255.255 && echo vlan169 configured
vlan169 configured
$ sudo ./minidns.py 169.254.169.254 &
[1] 35125
$ miniDNS :: * 60 IN A 169.254.169.254


$ dig @169.254.169.254 +short test.host
Request: test.host. -> 169.254.169.254
Request: test.host. -> 169.254.169.254
169.254.169.254
$ sudo kill 35125
$ 
[1]+  Exit 143                sudo ./minidns.py 169.254.169.254
$ sudo ifconfig vlan169 destroy && echo vlan169 destroyed
vlan169 destroyed
