Is something like this possible/realistic with IPv6?

I don't think so. How would you collect the list of addresses to scan? Maybe if you run popular CDNs or repositories, you could get a good chunk.

Yes. It's just harder. massscan can scan at absurd packet rates now.

A 10 GbE uplink gives you something on the order of a dozen mpps.

2^32 / 10 mpps = 7 minutes.

2^120 / 10 mpps = 4e19 centuries.

You're assuming you need to scan the entire IPv4 space, and limiting yourself to a single 10ge uplink. Neither of these are required.

What, no. It would take the lifetime of the universe to scan just a single ISP's IPv6 space. Every end user gets at least a 64 bits, 4 billion times larger than the current internet.
