   • 1 - UNICAST
     • TYPES
       • GLOBAL UNICAST (GUA)
         • STRUCTURE
           • GLOBAL ROUTING PREFIX
             • 2001:db8:acad:2:::254/64
               • 2001:db8:acad:2
                 • GLOBAL ROUTING PREFIX (NETWORK)
               • HOST-ID INTERFACE
                 • 254
                   • HOST-ID INTERFACE
             • 2001:db8:acad:2:::254/48
               • 2001:db8:acad:
                 • GLOBAL ROUTING PREFIX (NETWORK)
                   • DETERMINES THE SIZE THE SUBNET ID
                   • 48 BITS
               • 2
                 • SUBNET ID -
                   • 16 BITS
               • 254
                 • HOST-ID INTERFACE
                   • 64 BITS
           • SUBNET ID
             • /16 BITS
               • 256x256
                 • 65536
             • IPV6 WAS DESIGNED WITH SUBNETTING IN MIND
             • ISP
           • INTERFACE ID
             • HOST PORTION
               • RANDOMIC OR EUI MAC
             • STANDARD 64 BITS
             • THE ALL-1s CAN ALSO BE USED , BECAUSE BROADCAT ARE NOT USED WHITHIN IPV6
             • THE ALL-0s CAN ALSO BE USED , BUT IS RESERVED SUBNET ROUTER ANYCAST ADDRESS
         • CAN BE CONFIGURED
           • DYNAMICALLY
             • STATEFULL DHCPV6
             • SLAAC
             • WHEN USED , THE LLA OF THE ROUTER WILL AUTOMATIZALLY SPECIFIED THE DEFAULT GATEWAY
           • STATIC
             • ROUTER(CONFIG-IF)# IPV6 ADDRESS 2001:DB8:ACAD:1::1/64
         • DETERMINES THE SIZE OF THE SUB NETWORK
           • FAIXA 2000::/3
         • SIMILAR IP PUBLIC IPV4 ADDRESS
           • INTERNET ROUTABLE ADDRESS
         • UNIQUE AND ROUTABLE INTERNET
         • IANA ALLOCATES IPV6 CURRENTLY THREE BITS OF ARE BEING ASSIGNED
           • 001 OR 2001::/3
       • LINK LOCAL (LLA)
         • COMMUNICATE WITH OTHER DEVICES
           • SAME LINK AND ONLY ON THAT LINK (SUBNET )
         • FAIXA : FE80 :: / 10
         • USES FOR IPV6 LLAs
           • ROUTING UPDATE
             • NEIGHBOR ROUTERS
           • HOSTS USES LLA OF A LOCAL ROUTER
             • GATEWAY
             • TIPICALLY ONLY CREATE LLAs ON ROUTES
         • CAN BE CONFIGURED
           • STATIC
             • ROUTER(CONFIG-IF)#IPV6 ADDRESS FE80::1:1 LINK LOCAL
           • DYNAMICALLY
             • EXTENDED UNIQUE IDENTIFIER (EUI)
               • METHOD USES THE CLIENT MAC WITH ADDITIONAL BITS
             • RANDOMLY GENERATED
         • IS AUTOMATICALLY CREATED BY THE HOST WHEN IT BOOTS AND THE ETHERNET INTERFACE IS ACTIVE.
         • ZONE ID OR SCOPE ID
           • END OF ADDRESS WITH PERCENTAGE AND A NUMBER
           • EX : %21
           • ASSOCIATE LLA WITH SPECIFIC INTERFACE
         • CANNOT BE ROUTED BEYOND THE LINK WHICH THE PACKET ORIGINATED
