   • 1 - UNICAST
     • TYPES
       • LOOPBACK
         • ::1/128
       • UNSPECIFIED
         • ::
       • UNIQUE LOCAL
         • FC00::/7 - FDFF::/7
         • EVENTUALLY BE USED TO ADDRESS DEVICE NOT BE ACESSIBLE FROM THE OUTSIDE
           • INTERNAL SERVERS
           • PRINTERS
         • CHARACTERISTICS ULA
           • SITE OR BETWEEN A LIMITED NUMBER OF SITES
           • ARE NOT YET COMMONLY IMPLEMENTED
           • LOCAL ADDRESSING WITIN A SITE OR BETWEEN A LIMITED SITES
           • USED FOR DEVICES THAT WILL NEVER NEED TO ACESS OTHER NETWORK
           • NO GLOBALLY ROUTED OR TRANSLATED
       • EMBEDDED IPV4
     • PREFIX LENGHT
       • RANGE 0 A 128
         • RECOMMENDED USE 64 bit INTERFACE IF MOST NETWORKS
           • BECAUSE SLAAC - AUTOCONFIGURATION USES 64 bits FOR INTERFACE ID
       • PREFIX
         • 2001:0db8:000a:0000
         • NETWORK
       • INTERFACE ID
         • 0000:0000:0000:0000
           • HOST
           • /64
         • HOST PORTION
     • WHAT IS IT?
       • UNIQUELY IDENTIFIES AN INTERFACE ON AN IPV6 ENABLED DEVICE
   • 2- MULTICAST
     • FF02::1 ALL-NODES
       • NS & NA
     • FF02::2 AND FF05::2 ALL-ROUTERS
       • R1(CONFIG)#IPV6 UNICAST ROUTING -
       • RS & RA
         • SLAAC & DHCP STATELESS
     • SOLICITED NODE
     • TO SEND A SINGLE IPV6 PACKET TO MULTIPLE DESTINATIONS.
     • FF00::/8
     • WHATS IS IT ?
       • SEND A SINGLE IPV6 PACKT TO MULTIPLE DESTINATIONS
   • 3 - ANYCAST
     • ANY IPV6 UNICAST ADDRESS THAT CAN ASSIGNED TO MULTIPLE DEVICES
   • OBS : IPV6 DOES NOT HAVE A BROADCAST ADDRES ; MULTICAST GIVES THE SAME RESULT
