Understanding meaning of Network Types of Mainnet Statistic

Hello all,

I don't understand the point of view of the data contained in the network types

https://ethernodes.org/network-types

What does it mean? I.e. if you go on Residential, it shows a bunch of ISPS but surely it does not contain all worldwide ISPS where a node is hosted.

Does it contain ISPS that runs nodes or pool?

Can someone help?

Thanks,

T
