IP version 6
CE-143
CNE-0802
Background
IPv4’s addresses is only 232
IPv4 has minimum security mechanism IPv4 has no Quality of Service IPv4 did not support IP roaming
Advantage of IPv6 over IPv4
IPv6 has 2128 address space IPv6 simplify the header easier for router
to process IPv6 has more security features IPv6 has quality of service
IPv6 Addressing Scheme
16 bytes address Written in 8 group of four hexadecimal
notation separated by colon– 8000:0000:0000:0000:0123:4567:89AB:CDEF
First Leading Zero can be ommited– 8000::0123:4567:89AB:CDEF
IPv4 can be noted as– ::192.168.0.1
IPv4 vs IPv6 Header
Addressing
Global Unicast Address
IPv6 Address Allocation
Addressing Example
IPv4 and IPv6 Internetworking
many ways to do internetworking, 2 of them are:– Tunnel IPv6 in IPv4 network– Address translation
