IPv 4 Exhaustion n Available pool is 18 "/8 address ranges" n n n Each /8 has 16. 8 Million Addresses 203 already allocated 35 Reserved for special uses n Data from 5 -13 -2010, CNIT 202 E, link IPv 6 3
The End is Near
The End of the World n No Reprieve n n IANA will not re-purpose class D or E addresses for general use People who ask for IPv 4 addresses after exhaustion will not get them n Hoarding, scalping, and simple direct sale of IPv 4 addresses will begin soon

IPv 6 - IPv 4 Addresses n A hybrid format may be used when dealing with IPv 6 - IPv 4 addresses where the normal IPv 4 dotted decimal notation may be used after the first 6, 16 bit address elements:
Examples
Multiple Addresses n Note: Interfaces normally have two addresses, or even more Link-local n Global unicast n FE 80: : w. x. y. z
n Used by Ethernet
Example Interface MAC 00 -40 -63 -ca-9 a-20 IPv 6 Interface ID (EUI-64) : : 0040: 63 FF: FECA: 9 A 20 or : : 40: 63 FF: FECA: 9 A 20 link local FE 80: : 40: 63 FF: FECA: 9 A 20
