Well... You do have Windows Calculator there to help you out with the
stressful conversion of decimal to hex.
Otherwise, IMHO it boils down to simply an understanding that from the
router's view, ALL addresses are expressed in binary. For our benefit, IPv4
addresses are in dotted decimal, and IPv6 is in hexadecimal. I think it has
a lot to do with a technical understanding of these things in order to best
portray how to layout the information.
You certainly can ask the proctor as they are there to help clarify things.
However, they are not there to provide answers. So if their opinion/goal is
similar to mine, then you'll find an answer that informs you that there's
some more thinking to be done. Interesting enough, when you sit back and
think about questions you (collective you) have asked the proctor and
answers you received, both the good ones and the bad ones... Analyze
how/what you asked.
You'll find that when you asked questions demonstrating your technical
knowledge and seeking simple clarification, the answers were "good". When
you asked questions more vague, which came across as you didn't know
something (and very well may not have) the answers were more "irritating".
It's all perspective. But the best part is to identify those areas needing
clarification and seek out those answers! No doubt that it takes the fun
out of it when those answers aren't readily available in the lab itself, but
make it a personal quest to find all those answers after an exam!
Even if you pass the lab, if there are outstanding questions, find the
answers! The learning doesn't end with the number.

Honestly Scott,
This kind of question is best handled/resolved by the Proctor. If you're
unlucky to meet a "Not-So-Totally-Happy" Proctor, then he will say "Do what
you think is right" ... I hate it when I hear that in the Lab!!!!!
Drive me nuts!
To me, such a question has no bearing with a CCIE's level of technical
ability, just one of those semantics you can't afford to miss out on.
Ofcourse, one will have to know how to convert to HEX in the first instance,
even in the dreams.... Yea, I remember doing all those while sleeping
before, well my brain nerves was still working while asleep ...
This was long time ago in my grad school.
Many Thanks.

Being that IPv6 is a hex-based address, I would convert it to hex to have
the same binary equivalent.

Subject: IPV6 question understanding
Hi all,
I have one question,
if on the IPv6 section, they ask you to enable eui-64 and they give you
subnet let's say 2001:aaa:111::0/64 but they tell you, you should use
IPv4
address's 3rd octet in the network of IPV6.
and let's say you have in IPv4 25.25.56.1/24 do you just take 56 and put in
network as following: 2001:aaa:111:56::/64 or you translate 56 to HEX and
put 38(hex of 56) -> 2001:aaa:111:38::/64
I think I need to use directly 56, but I would like some to confirm me this.
Many thanks,
