First you'd have to have a site that links directly or indirectly to every
other site.  Perhaps the results of a overly general Google search or maybe
the root dns servers.

Next you'd have to set options -> Limits -> Maximum external depth > 1
Billion

Finally increase your machines disk capacity.  A few exabytes should do it. In
2002 the internet was 532,897 TB bytes.
