What are the key differences between IP version 4 and IP version 6? or Should I still use IP version

IPv6 is like IPv4 on steroids. More addresses, better routing, built-in encryption. But switching? Eh, not urgent unless you’re out of IPv4 space.

Fun fact: Some sites (like Facebook) load faster over IPv6. Test yours at ipv6-test.com.

But don’t stress—most networks are hybrid anyway.
