IPv6 is similar enough to IPv4 that it makes it easier to learn than if
it were a completely new and unrelated protocol.

It's different enough that you need to take each of the concepts and
practices that you know and have used for IPv4 for many years and try
to objectively evaluate whether they're still valid for IPv6. IPv6 has
features that IPv4 has never had, but have existed in IPX and Appletalk
since they were designed many years ago. If people have the time,
learning about those protocols might help with more easily learning
about IPv6.
