The thing about IP and therefore with IPv6 is it's not just an address format - it's a set of protocols and practices so a lot of it changes.
Address asignment in an IPv6 world is more complicated - you can do DHCPv6, or your can do stateless auto-config. Which should you choose and when? Many other aspects of the stack require more knowledge.
And THEN you ALSO need to understand how v4 and v6 interacts so you can provide suitable compatibility - the various different methods of tunnelling and negotiation.
- escalt 6y agoUsing SLAAC is the way to go in most cases. DHCPv6 should only really be used when you have a network that is for some reason smaller than a /64. In my opinion you shouldn't really bother with compatibility. Just do dual stack and maybe NAT IPv4 if necessary. For my personal use cases IPv6 just proved to be much more versatile than IPv4. It did take some getting used to since it's approached differently, but learning it is very worth it and also helps using IPv4 better
- oarsinsync 6y agoLook at all the additional optional bits DCHP offers in terms of being able to communicate additional information to clients to configure themselves. Two big ones that stand out are timeservers and network booting parameters. SLAAC is only a drop in replacement in the (typical) home.
