Mobile IPv6 for earth

Studying for the CCNA Exam and the next topic is ipv6. I remember my teacher explaining that the last ipv4 address was given out in November 2011, and the number one reason was the proliferation of smart phones requiring an IP address. Did some reading on cell phones in general, curious on what's new because I don't even own one myself, and my brother keeps bugging me that I'm missing out (What, on Angry Birds?) and they mentioned about mobile IP and I put the two ideas together.... well they must be using IP v6!

Mobility driving the requirement to maintain the same IP address while moving seamlessly across different networks. That's pretty cool. Read all about Mobile IP. 

So do all the addresses really start with 2 (for planet earth?). The prof also had a few other wacky ideas too, like he could write a book about IPv6 in less than page, and that to  make millions in IT just sign up to be the IPv6 networking guy. It would be easier job ever. Really? So I guess this is my book on IPv6: (Be careful with the use of colons, they mean something!)

The IPv6 address is formed from 32 bits of hex.
The global unicast begins with 2000

The Link Local Address refers to the physical link
- not for forwarding datagrams
- for neighbor discovery and route discovery
- begins with FE80 <internal mac address> or FFEE

The Loopback address is ::1 which means all preceding zeros.

Unspecified address
- a host looking for his own address
0:0:0:0:0:0:0:0 or ::

Stateless Autoconfiguration
prefix + interface ID

Stateless DHCP

HOW TO Enable IPv6 on a router
usage: ipv6 unicast routing
usage: ipv6 address 2001:db8:c18:1:: 64
(the first part was the global address, no need to write sequential or preceding zeros, the 64 means eui-64)
* Specify the 64 bit prefix by using eui-64 if you want the router to derive interface ID portion from mac addres

* You can automatically get the link-local address FE80:
show ipv6 int ethernet 0

RIP based on RIPv2
* uses the multicast group FF02::9
