IPV6: Quick straight forward notes on differences in modes for exam day!

Going to cut right to the chase here for exam day what you will need to know without a lot of explanation, as I’ve been reading the white papers for my second attempt this Friday, and there are just some things to know without knowing all the “why.”

NTPv6 – This does the same function as NAT for IPv4, only it does it ONLY for IPv6. So if you are asked to explain what it does, it allows communication between IPv6 networks (and if they aren’t dual stacking they aren’t talking)

NAT64 – This could be a local server in your building, or a server at your ISP, that translates V6 addresses to V4 addresses, so hosts can communicate without using Dual-Stack technology themselves.

Stateless NAT64 DOES NOT CONSERVE IPV4 ADDRESSES, 1:1 translations, no IP bindings done in this mode, requires manual or DHCPv6 address to assign an IPv6 address

Stateful NAT64 DOES CONSERVE IP ADDRESSES, 1:any usable translations, creates states or bindings for every entry requiring one to translate between IPv6 and IPv4

IPv6 Tunneling – As posted earlier about IPv6 there are some different Tunneling methods, but all of them do require devices capable of Dual Stacking, remember that on exam day

Dual Stacking – Ability of a host to speak IPv6 and IPv4 with other hosts with the same capability

That is all, remember that information, it may save you a few points on exam day ^
