How important is IP address distribution with self-hosted prelanders


For those who host your prelanders on your own domains, how much importance do you place on spreading them across different ip addresses and/or hosts?
I’m about to start a thing and it would be easiest to just host all the prelanders on one host. I don’t think buying a bunch of different IP from the same host would be very helpful, maybe for a small number of landing pages, but it’s not sustainable for this plan. I’m thinking of getting a bunch of low-end hosting. I thought about using the same type of service that the guys that do PBNs use, but I think that’s overkill for what I need.
Any thoughts, tips, or suggestions?
