How to add another IP to server? How to add IPV6 to server?

I have changed from VestaCP to CWP, at the moment I saw that CWP is more complex but also more powerfull, at the moment I'm struggling with a basic thing adding a extra IP to my server. Anyone can help me with that?

Also very important how can I add an IPV6 to my server?

I'm using Centos 7.

Here from the wiki:
http://wiki.centos-webpanel.com/add-additional-ip-address

I have done that, if I ran ifconfig I can see something like this

Code: [Select]

[root@mercury ~]# ifconfig

If I access using ipv4 in chrome I get the CWP page but if I tried the same using ipv6 I get an erro  "ERR_CONNECTION_REFUSED"

Hello.

The CWP does not use IPv6 for now. Probably it will be in a future release.
