How to assign multiple fixed ip address for one domain?

Question

I'm running dnsmasq,

address=/chat.freenode.net/130.239.18.172
address=/chat.freenode.net/140.211.167.105

But seems dnsmasq only recognize the last record, what should I do?

Answer 1

Create a file, say /etc/hosts.chat.freenode.net, that has the same format as /etc/hosts file and list all IP addresses with name in this file:

130.239.18.172 chat.freenode.net
140.211.167.105 chat.freenode.net

Then add to the dnsmasq.conf the following line:

addn-hosts=/etc/hosts.chat.freenode.net

Or put these two lines into /etc/hosts if dnsmasq is set to read in the /etc/hosts.

Then restart dnsmasq

Enjoy.

Answer 2

Copy the existing ifcfg-etho to ifcfg-eth0:0 and change the existing IP to your virtual IP (the one you want to add).

It can be found at /etc/sysconfig/network-scripts.

Restart the network and try to ping the virtual IP.
