Do you use IPv6? If not, IPv6 put simply is the new and improved ip addressing system. IPv4 is over 20 years old and with more computers and servers coming onto the internet, demanding more address space, we run out of addresses. But, ipv4 addresses are 32 bit, thus not allowing any more than 4,294,967,296 ips. However, ipv6 is 128 bit and will allow approximately 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses. A /64 prefix (which is what a general home user gets) would have around 18,446,744,073,709,551,616 usable ips. Here is a basic subnet table (borrowed from linuxreviews.org):

Now, if you want cpanel to be ipv6 compatible, please post on this bug:
