   Hi Rick!

   It is simply a new version of IP.   
   We are out of stock of IPv4 addresses, and there are plenty of IPv6 addresses.   
      
   There are people that only have a public IPv6 address and a private carrier   
   grade NAT IPv4.   
   If you only have an IPv4 address, then you cannot communicate with them any   
   more.   
      
   So the advantage is that you can keep communicating with hosts that only have   
   public IPv6 addresses.   
      
   And as there are no longer very cheap/free IPv4 addresses available, the move   
   to IPv6 will be much stronger in the future.   
      
   For now you simply need IPv4 to address hosts with A records, and IPv6 with   
   AAAA records. Normally servers will add both nowadays. (but for how long ...)   
      
   ricsi@menedetter:~$ host menedetter.net   
   menedetter.net has address 45.142.176.108   
   menedetter.net has IPv6 address 2a03:4000:4a:c5f::1   
      
   ricsi@menedetter:~$ host facebook.com   
   facebook.com has address 157.240.17.35   
   facebook.com has IPv6 address 2a03:2880:f15b:83:face:b00c:0:25de   
      
   Plus you encode "messages" into your address like Facebook does above, or some   
   fido nodes do:   
   ricsi@menedetter:~$ host fido.ricsi.priv.at   
   fido.ricsi.priv.at has address 45.142.176.108   
   fido.ricsi.priv.at has IPv6 address 2a03:4000:4a:c5f:f1d0:2:310:31
