I have a /112 of IPV6 addresses. CPanel has already assigned some of them for websites. I want to set something up so I have a dedicated IPV6 mail IP like I do for IPV4--particularly so I'm not trying to keep up with whichever IPV6 address Exim decides to grab in order to send mail. Is it possible to manually tell CPanel to bind an IP address within that /112 range to the server permanently, whether an account is using it or not? Or, alternatively, tell CPanel to assign it similar to what we can do with V4 addresses so I can make the appropriate DNS entries to make that possible? Any help here would be appreciated.
