Binding multiple IP Addresses to same NIC

Harlin · 08-21-2005, 04:50 AM

I have a nic, eth0. I would like to bind two IP Addresses to it:
192.168.115.21
10.10.1.21

How do I do this?

Thanks,

Harlin

Thanks. Just in case the link changes here is the info in brief... type
ifconfig eth0:0 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
(obviously replace the x's with your second ip address, and the y's with the mask for it.). you can add this line to /etc/rc.d/rc.local so that it is run each time the pc starts.
no doubt if you want a thrid ip address you can use eth0:1
and if you want the second ip on eth1 use eth1:0

Hi!
I had done that by useing the IP command:
ip addr add xxx.xxx.xxx.xxx/nn brd + dev eth0 label eth0:0

where xxx - your IP
/nn - netmask

Works fine!
