    Issue IPv6 ranges not working as they should

    Hi, When I add an IPv6 range like 2a01:4f9:2b:f810:0:0:0:1 -> 2a01:4f9:2b:f810:ffff:ffff:ffff:ffff (Mask /64), it will only use the 2a01:4f9:2b:f810::1 address for all of the sites, and not allocate one IP per site from it, why's that? I don't think that's how it's supposed to work?

    Question Only IPv4 added to hosting package by default, IPv6 needs to be added manually

    Hello, It seems that all the hosting packages I add will only get the IPv4 of the server assigned. Why is the IPv6 not added by default? Can this be done via the API maybe?
