Great post, thanks! I was hopeful the internet archive had an old snapshot of 7427466391.com, but, no such luck:

Does anyone know or recall what the even harder problem hosted on this website was?

I'd probably just look for the numbered IP addresses with these 10 digits that serve up NS or SOA records, and go from there.

The https://apod.nasa.gov/htmltest/gifcity/e.2mil URL still works, and now I'm really curious about why there are 2 million digits of e on APOD (Astronomy Picture of the Day)
