I summarised this from techrepublic
1: IPv6 addresses are 128-bit Hexadecimal numbers
example FE80:CD00:0000:0CDE:1257:0000:211E:729C
2: Link local unicast addresses are easy to identify
example unicast addresses always begins with FE80
Multicast addresses always begin with FF0x
3: Leading zeros are suppressed
example this address FE80:CD00:0000:0CDE:1257:0000:211E:729C is thesame as
this FE80:CD00:0:CDE:1257:0:211E:729C
4: Inline zeros can sometimes be suppressed
example this address FE80:CD00:0000:0000:0000:0000:211E:729C is thesam as
this FE80:CD00::211E:729C
5: Loopback addresses are funny looking addresses
example 0000:0000:0000:0000:0000:0000:0000:0001 0or ::1 when suppressed,
or 127.0.0.1 in IPV4
6: You don’t need a traditional subnet mask
7: DNS is still a valid technology
8: IPv6 can tunnel its way across IPv4 networks
9: Not all switches and routers support IPv6
10:Windows Vista has IPV6 installed by default
