IP aliasing is a special configuration of your dedicated server network, which enables you to associate several IP addresses to only one network interface card.



The aim is to create a virtual interface above eth0, which will be named eth0:0 and will attach the additional IP or Fail over to your network interface. Here are the explanations for the addition via SSH. You can also do it directly via your webmin, ‘others’ section, then files management

First of all, replace the device name, then the existing IP by the failover/ additional one that you have received by email:

At the time of reboot, the interface will automatically be assembled.

If operations 1 to 3 have been correctly carried out, the IP shown in eth0:0 file must be pingable from another machine and answer to the requests.

If you have several additional IPs; you can renew the operation by using eth0:1, eth0:2 and so on.



If after handling, your IP doesn’t answer to the pings, please contact our support.

You can either use nano or vi. Under Gentoo, an alias is directly added in eth0. We don’t create any eth0:0 interface (as under Redhat for example)

Important: default IP of the server must remain config_eth= on the same line. In order to make sure that some specific handlings in VHSCLOUD work correctly



After netmask 255.255.255.0, Press Enter and add your IP (XXXXXXXX have of course to be replaced by your Ips)

You must add:

Your /etc/conf.d/net file must contain the following:

In order to ping your IP-failover, you just have to start the network interface again

If operations 1 to 3 have been correctly carried out, the IP shown in eth0:0 file must be pingable from another machine and answer to the requests.

You can therefore insert an additional IP line by line. However, it is important that the default IP remains on the same line as config_eth0

If steps 1 through 3 were carried out correctly, the IP shown in the file must be pingable from the outside and answer the queries.

If after handling your IP does not respond to pings, please contact support.

1. We edit the file /etc/ips :

2. We add the ip to the file:

3. We add the ip in /etc/ipaddrpool

4. We restart the service managing failover ips :

For HG servers which are delivered with 2 Ip addresses and 2 network cards, it's necessary to add the fail-over Ip in the routing rules:

A example file on a HG server with Gentoo distribution gives:
