The IPv4 price is still tiny, and you anyway have to pay for it since going IPv6-only is not viable for a service in 2024 still. It's not going to significantly move the needle towards IPv6. And the price hikes will also be tiny.
Well, my employer’s AWS bill is in the region of $20m/year and the additional IPv4 tax is on track for adding an additional $250k to that for no benefit at all.
quarter million sounds enough to pay an engineer to make it work w/o v4. then again it's only a 1% increase and might not be worth the effort.
Well, 1.25% is quite tiny. And I'd bet you're not moving to IPv6 anyway, at least not entirely, since a good amount of people are probably accessing your services over IPv4-only connections.
