Angelina,

Scanning all ports will take a long time. At 203 seconds, you're 
averaging 322 ports per second. That's not bad. Scanning a /64 will take 
a *very* long time, since that's 64 bits of network address space, 
equivalent to 2^32 IPv4 /0 internets. You will not finish host 
discovery, and if you use -Pn you will be scanning thousands of ports on 
billions of hosts that do not exist.

Give our targets-ipv6-* scripts a try, or the ones from Raul Fuentes
