  5. DNS FTP WWW TELNET Streaming BBS NTP “GO” game And others Application available for v6

  6. Pro & Con • High bandwidth – we do this way at this stage • QoS - • Security – Source address authorization • E2E – no NAT hopefully • Connectivity to v4 world - yes • More applications – still need time to prove • Free of charge - no • User number growth rate – we will see
