Adding an IP address

If you've been assigned one or more additional IP addresses, here is how to add them.

Adding an IPv4 address on a Ubuntu 14.04 LTS VPS

First open your interfaces file for editing:

$ sudo nano /etc/network/interfaces

You should see your main IP address described for IPv4 and IPv6. The IPv4 part looks something like:

    # The primary network interface
    auto eth0
    iface eth0 inet static
    address 85.119.12.34
    netmask 255.255.248.0
    gateway 85.119.80.1

Go to the end of the file and add information about your new IP. It doesn't need a gateway and you can use 255.255.255.255 for netmask:

    # The secondary network interface
    auto eth0:0
    iface eth0:0 inet static
    address 85.119.56.78
    netmask 255.255.255.255

For each additional IP, use eth0:1, eth0:2 etc.

Once you're finished, press Ctrl-X and save your file. Then shutdown your machine:

$ sudo shutdown now

You will then need to reboot your machine by logging in via the Xen console. Get your details from the Bitfolk Panel:

Xen shell> ssh you@you.vps.bitfolk.com

Once logged in you will see the Xen command line prompt. Try

Xen shell> boot

If it complains that an instance already exists, and you've waited sufficiently long that the machine should have shut down, do

Xen shell> destroy

then

Xen shell> boot

You can now log back in to your VPS and your new IPs should work.
