Hands-On IPv6 Lab Setup

The article states that a /48 allocation lets you have 32,768 /64 subnets.
The correct number is 2 to the sixteenth, which is 65,536 /64 subnets.

To make matters clearer, I would also like to point out
that in the Cisco skeleton configuration listing (Figure 7)
the names "CISCO WAN PORT IP ADDRESS"
and "YOUR IPV4 LAN ADDRESS" are used interchangeably.
Also "ADDR OF IPV4 LAN ROUTER" refers to our firewall's internal IPv4 address.
The IPv4 network that connects our router and our firewall is the 10.10.10.0/24
and the IPv4 lab network that we will use is the 192.168.6.0/24.
These should have also been more thoroughly depicted in Figure 6.
(The corresponding IPv6 networks are thoroughly identified in the article.)
This article would have been better, if there were two figures in place of Figure 6.
One figure would depict all (and nothing but) IPv4 addressing
and the other figure would depict all (and nothing but) IPv6 addressing.

The article also provides references to John Howie's articles
"The Inevitability of IPv6" Part1 and Part 2
and these two parts suffice for the article's purposes.
But there is also a Part3 (InstantDOc ID 100618)
that I would also like to be mentioned.
You see, John Howie's Part3 was only published to the web,
so fewer people know about it. The article's title is
"Managing Your Migration and Transition from IPv4 to IPv6".
