- We've covered a lot of ground in this course,
and though the journey has been tough at times,
it's been well worth it,
but our networking expedition isn't quite over yet
because we still have the vastly important frontier
of IPv6 to explore.
Understanding IPv6 is vital
to meet today's real-world networking challenges
as well as to ace the exam.
This final section is brimming with all the IPv6 information
you'll need to complete your CISCO exam trek successfully,
so get psyched.
We're in the home stretch.
I probably don't need to say this, but I will anyway.
You absolutely must have a solid hold on IPv4 by now,
but if you're still not confident with it,
or feel you could use a refresher,
just go back to the chapters on TCP/IP and Subname.
And if you're not crystal clear on the addressing problems
inherent to IPv4, you really need to review
the last video, Network Address Translation
before we decamp for this chapter's IPv6 Summit Push.
People refer to IPv6 as
the next-generation internet protocol, and it was
originally created as the solution to IPv4's inevitable
and impending address exhaustion crisis.
Though you've probably heard a thing or two
about IPv6 already, it's been further improved
in the quest to bring us the flexibility,
efficiency, capability, and optimized functionality
that can effectively meet our world's
seemingly, insatiable thirst
for every evolving technologies increasing access.
The capacity of its predecessor, IPv4,
pales in comparison, which is why IPv4
is destined to fade into history completely,
making way for IPv6 in the future.
The IPv6 header and address structure
has been completely overhauled,
and many of the features that were basically
just afterthoughts and addendums in IPv4
are now included as full-blown standards in IPv6.
It's power-packed, well-equipped
with robust and elegent features,
poised and prepared to manage the mind-blowing demands
of the internet to come.
After an introduction like that,
I understand if you're a little apprehensive,
but I promise to make this chapter
and its VIP topic pretty painless for you.
In fact, you might actually find yourself enjoying it.
I definitely do.
Because IPv6 is so complex while still being so elegant,
innovative, and powerful, it fascinates me
like some weird combination of a sleek,
new Aston Martin and a riveting futuristic novel.
Hopefully, you'll experience this chapter
as an awesome ride and enjoy watching it
as much as I did filming it.
