  1. IP version 6 CE-143 CNE-0802

  2. Background • IPv4’s addresses is only 232 • IPv4 has minimum security mechanism • IPv4 has no Quality of Service • IPv4 did not support IP roaming

  3. 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

  4. 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

  5. IPv4 vs IPv6 Header

  6. Addressing

  7. Global Unicast Address
