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

CU, Ricsi
