What’s the main difference between IP version 4 and IP version 6? or Can someone explain the key diff

IPv4 vs IPv6 isn’t just about more addresses (though that’s the biggie). IPv6 has built-in multicast, so streaming is way more efficient.

And no more NAT! Direct connections everywhere. Feels like magic.

But yeah, the syntax is wild. Pro tip: use `ping6` instead of `ping` for IPv6 testing. Also, check out [IPv6-test.com](http://ipv6-test.com/) to see if your setup’s ready.
