When you purchase extra IPs, or simply request the extra free usable IPs, you will need to configure them.
To begin configuring your newly assigned IP, first note said IP.
i.e. xxx.xxx.xxx.xxx (Replace this with the assigned IP.)
Connect to FTP with your SSH info. We reccommend FileZilla.
Navigate here: /etc/network
And download interfaces to your desktop.
ALTERNITIVE: You can use the built in text editors from the SSH console, like Putty.
Type the following into SSH:
sudo nano /etc/network/interfaces
Then make the following changes. (Make these changes for both editing methods.)
You will need to add this to the file:
iface eth0:1 inet static
Replace xxx with the new assigned IP.
Where there is xxx.xxx.xxx.anumber, only replace the the first three strings of the new IP.
i.e. for gateway: 188.8.131.52
When adding any more IPs in the future, changeauto eth0:1 and iface eth0:1 inet static to auto eth0:2 and iface eth0:2 inet static, increase one number per IP.
After this change is complete and saved, you must restart your networking!
sudo /etc/init.d/networking restart
