How to add a virtual IP in MacOSX?

Posted on 11. January 2011 by fsormok

To add a secondary (virtual) IP address to an existing interface use the following command:

sudo ifconfig lo0 inet 192.168.0.1 netmask 255.255.255.0 alias

to remove it again use:

sudo ifconfig lo0 inet 192.168.0.1 netmask 255.255.255.0 -alias

simple as thatÂ 🙂
