I have no visualization capability at all, but I am good at networking.

Not sure if this helps anyone but when I think about networking, I think about how packets have “tickets” and the network operates like a railway — if a packet or network flow doesn’t have the right ticket, it can’t go somewhere. And, inversely of course, if it does have the correct ticket it can get somewhere. Points where routing occurs are like railway stations or (appropriately enough) switchyards. What ticket you have determines where you go.

This method might not work for everyone, but it does for me. I am very non-visual so I simply cannot think about it any of this in visual terms as many people do. It’s not just hard; it is impossible for me.
