is there map for ipv4 internet?

sorry my poor title but I don't know how to express my intention.

In ipv4 there are 2**32 addresses right?

and then if I send 1024 packets per second I could check all the devices of the internet in 1165 hours to create map of the internet. with it I want to make a topology of the internet

it's not that bad, if I go with multiple computers like raspberry pie it would be more faster.

if it's not me but somewhat organization or people and they have enough time, it could even scanning all the ports of all the devices of the internet..!

is my thought a daydream? or somebody already did it? please let me know! I'm curious
