Well, what address format would you propose that would make it better? Let’s talk actual workable detailed proposals rather than just hand-waving.

We already have a number of such solutions:
	NAT64
	464XLAT
	B4/AFTR
	etc.

I haven’t had that much trouble.

Well, your abuse of the phonetic alphabet might be part of the problem…

Foxtrot, Alpha, Charlie, Echo, colon,  Bravo, Zero, Zero, Charlie has worked relatively well for me.

Really? I’ve actually had more confusion over this… especially five vs. nine (unless I resort to pilot-speak which often confuses them even more).

two, five, zero, point, two, zero, six, point, one, seven, six, point, one, nine, two will almost invariably result in some random member of the set:
	290.206.176.152
	250.206.176.152
	250.206.176.192
	290.206.176.192

And that’s an address not particularly fraught… Consider, instead:

	193.159.155.159

Sometimes I get lucky with one, niner, tree, point, one, fife, niner, point, one, fife, fife, point, one, fife, niner. However, that’s rare.

I guess it depends in part on who you are speaking with.
