Or, if you have different sites on different hosting accounts, you may want to look at something like a VPS, where you can host them all. Sometimes placing them all on one better place is actually cheaper (on a pure what you get billed) than spreading them out across multiple cheap hosts. Worth looking at anyway.
I keep them on different hosts and take other measures to keep groups of them unconnected to each other as a part of my personal low risk tolerance program. I have had a site banned in the past because of a programming error in the Google algo, not my code, and I wouldn't want to risk having all my sites getting deindexed.
It got sorted out after a few months but apparently patching the algo code to reindex a single mom and pop type site isn't always at the top of the priority list for the Google engineers.
I have also had sites hacked. It just feels safer to me to have them spread around and unconnected.
