Is there an open source ip database like whatismyipaddress.com/?

Question

open source

In particular, the display for ip connection is of interest: broadband or datacenter, display of the provider and country (I can get the country from geo ip myself).
In particular, I use this data to filter out bots, if the Connection field contains datacenter, then it’s a bot, or if the dude is from a verison or at & t provider, then it’s a good one.
I'm even ready to buy such a base
Now I use whatismyipaddress.com/ , I have to go through a proxy, as they limit the number of requests, they don't give api, they don't sell the base.
