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

IPv6’s addressing is hierarchical, so routing tables are smaller. ISPs love that.

But the difference between ip version 4 and ip version 6 that bugs me? DNS. AAAA records feel like an afterthought.

Tool tip: `dig AAAA example.com` to check IPv6 DNS. Also, [test-ipv6.com](https://test-ipv6.com/) is clutch for troubleshooting.
