Neat! Would have been a real head scratcher. Thanks for sharing.

Great post, thanks! I was hopeful the internet archive had an old snapshot of 7427466391.com, but, no such luck:<a href="https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20130815000000*&#x2F;http:&#x2F;&#x2F;www.7427466391.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20130815000000*&#x2F;http:&#x2F;&#x2F;www.74274...</a>Does anyone know or recall what the even harder problem hosted on this website was?

The <a href="https:&#x2F;&#x2F;apod.nasa.gov&#x2F;htmltest&#x2F;gifcity&#x2F;e.2mil" rel="nofollow">https:&#x2F;&#x2F;apod.nasa.gov&#x2F;htmltest&#x2F;gifcity&#x2F;e.2mil</a> URL still works, and now I&#x27;m really curious about why there are 2 million digits of e on APOD (Astronomy Picture of the Day)

I&#x27;d probably just look for the numbered IP addresses with these 10 digits that serve up NS or SOA records, and go from there.
