I have a client who specifically wants to use a certain host. The plan they want offers a dynamic IP, not static. To be clear, this is not about shared IP addresses - this is about an IP that changes periodically.

I having trouble finding any information on whether this is to be considered a ranking factor or not. Anyone have any knowledge on the subject?

As I think there is some misunderstanding about the IP address. A dynamic IP is valid for the internet connection. when it comes to hosting services it always gives you a static IP. Since All domain need a Nameserver to propagate and all name servers propagate through a set of IP so it is not possible for having a dynamic IP to host a website. The moment the IP will change the domain will stop propagating and your website will not load.

All web servers take some range of IP to host websites. If you have a dedicated server you will be able to have a dedicated IP which will not be shared by another website. And in case of a shared hosting the same IP is used to host a number of websites. Even in shared hosting you can demand for a dedicated IP which can be used by you only.

Bad. Bad bad bad bad bad.

Seriously that's just completely ridiculous. The only reason for a dynamic IP is because someone's hosting this in their basement on a home internet connection. That's just a bad idea right there. But even then, fer cryin' out loud you can normally pay $10 a month and get a static IP at home.

Tell your client if they want to use their receptionist's 16 year old son as their 'hosting company' then they're about to get what they paid for.

It doesn't matter if it's a ranking factor specifically. Every time Google tries to spider it, it's going to be on a different IP. Pretty good chance that they'll get a bunch of 404 when they try to spider the last IP the site was hosted on instead of the current one. And so on with the technical issues - lots of ISP's cache IP addresses and completely ignore your cache settings which means that not only will Google not find you half the time, your visitors will be seeing 404 not found errors as well. Yes, there are solutions to this, no they're not suitable for a real website.
