[AusNOG] cPanel IPv6 = Overhauled

[Luke Thompson]

G'day,

After meetings, back-and-forth and testing spanning over half a year, 
we're glad to report that true IPv6 support has arrived in cPanel+WHM!

https://blog.apnic.net/2025/05/21/cpanels-ipv6-overhaul/

There's no longer the need for there to be a "server prefix" and a 
separate "range prefix", they can now be nested, enabling true SNI.

Further, when enabling for sites, you can either use SNI via the 
server's shared v6 addy, or issue a /128 from said prefix.

Ultimately this allows for far cleaner dual-stack deployments for the 
Hosting world, with no messy workarounds!

This is now available on all release tiers, as v126 has been promoted to 
LTS you can get going with v6 now.

Many thanks to APNIC, WebPros and Global Secure Layer for your 
assistance throughout these works.

Cheers,

Luke Thompson, CTO
