use wget to fetch the index.html into a file then grep -i its content.

I'd suggest to learn how to use a search engine and stop
multi-posting...

How many decades will it take a PC to search half the Internet that way?

Not quite half.

Routable addresses are (theoretically):
the range 1.0.0.0/8 - 223.0.0.0/8
minus:
10.0.0.0/8
127.0.0.0/8
169.254.0.0/16
172.16.0.0/12
192.0.2.0/24
192.168.0.0/16

In the meantime, however, this request seems an awful lot like what bots
do to look for new servers they can infect.

That comment brings up another point. With the proliferation of
virtual named hosts, going by IP address is going to miss a lot. I
have multiple domains on my server, and in some cases multiple hosts
per domain. And the default container (which is what access by IP
address without a host name or with the IP address as host name would
get) does not contain any of those sites.

Ok, that I can ensure it's not for. It's actually more a hypothetic question
rather than a request. I just wanna know stuff like that

"I want to know how I make a script for scanning the entire internet
for one unique index.html file (I got the index.html file I'm looking for)
and then whenever it finds a match to the index.html file saving the
results into a textfile, all scanning done using standar http port 80.
So the end result will be a text file contaning the ip addresses found
matching the index.html I got"

Doesn't sound like a hypothetical to me.. sounds like you are doing
something specific (and, suspicious).

That is not the entire internet, as already mentioned.

An alternative approach might be to find some sort of fingerprint (unique
segment) in the index file, and utilize a search engine (such as google) to try
and match the fingerprint. (The search engine may provide an API that can be
utilized.)

The search will of course be limited to pages indexed by the search engine,
but you will need a lot of computing power and sufficient bandwidth if you
want to outperform google. (There are billions of pages to process.)

Regards,

Mark.
