Unless you're working on a really strange OS, for normal client software, v6 doesn't work any differently than v4. It's IP with a larger address space.

It's only when you get down to the level where you're doing things like acquiring an address [0] that you need to worry about the differences.

[0] Or -I guess- doing multi/broadcast. IPv6 substantially simplified broadcast. Send your packet to ff02::1 [1] to get the same functionality as IPv4 broadcast.

This is a great comment and the kind of content that i think should be put in a single "fact sheet". I might give it a try and see if people find it useful...i have a 13 hour plane ride coming up, sounds like fun :(

Things like that have been done before. [0] It seems to be difficult to get good Google juice. Perhaps your writeup will be the one that cuts through all of the SEOed clickbait and is the go-to guide for good IPv6 info. :)

However, don't let me discourage you from taking on the task! It's sure to be edifying... or -at least- something productive to do to while away that obscenely long plane ride.

Best of luck!

Wow this is a great resource you've linked to, thanks! It's pretty long and probably a touch more than most people want/need to read, but it is very complete.

Unrelated, yeah Sydney to Toronto Canada (via SFO) terrible flight.
