On linux boxes it is possible to add multiple ip addresses to the same network interface.

It's achived with the following command:

ip addr add dev eth0

Is there any way to to the same with OS X ?

I've tried to put multiple ip addresses (comma separated like the dns) in System Preferences / Network with no luck...


Yeah, it's pretty easy. Open System Preferences, go to Networking, then click the Plus sign under the left bar. Choose the interface, give a name to the adapter configuration you're creating, then press OK. You will have to provide manual configuration of IP address and DNS for the second entry -- DHCP won't work for it, because it shares the same MAC address as the original entry, so the router won't issue it another address. Click Apply when you're done, and enjoy. Your adapter now has two IP addresses.

  • How can it make it work with a browser? I mean, I can ping or telnet using the new address, but I can't connect using the browser... – yeyeyerman Feb 26 '16 at 11:32
  • You can reorder adapters in order of preference by dragging and dropping them. – zneak Feb 26 '16 at 15:19

sudo ifconfig en0 alias up

  • Thanks! ... And to remove them? – F. Hauri Jul 16 at 10:59
