Although IPv6 has been in regular operation for almost 20 years, its saturation within corporate networks is still relatively low. Switching from IPv4 to IPv6 is a long-standing process that requires good planning and involves parallel operation of the two protocols.
Even if there is no way around IPv6 for administrators, the official predecessor IPv4 will still be in the networks for many years. That’s why you should have a closer look at the hurdles of IPv4.
Daily work with IPv4 and its subnets can be a real struggle. Do you know how many addresses are available in the 255.255.224.0 subnet? Me neither! Converting .255 or .224 in binary is easier, but (usually) also not the daily business of an IT admin.
