When Ches was at Bells Labs/Lumeta he created a daily map of the (whole)
Internet.
Using a BSD machine sans firewall. Presented a paper at SAGE-AU 2000
[Gold Coast].
APH here in Canberra was the first (and almost only) site that asked not
to be mapped ;-)

Ches is the Cheswick  of Cheswick and Bellovin: "Firewalls and Internet
Security"

He used to give 'research' copies of his database away... Webpage says
he doesn't run the mapping any more.
[he might give you his code or some hints if you were to ask]

The smart part of what they did was the actual mapping - seems nobody
else can map millions of nodes :-)
