I’ve got some parked domains on a variety of other registrars that I’d consider transferring into Cloudflare. Some are defensive, i.e. domain names close to domains for active sites. Some are just to reserve for a future application that may never come into being. All of these would be added at the Free tier because there’s no real site there.
I’d prefer to pay Cloudflare the annual registration fee than GoDaddy, NameCheap, etc., partly because the fees are always lower and partly because I hate the practice of other registrars giving a cheap first year, then out years being double or triple the first year price.
However, I don’t know if having a bunch of $0 revenue parked domains is something Cloudflare is okay with. As strange as this sounds, I sincerely want Cloudflare to make some money on my registrations and don’t want to burden it with parked domains if that’s not okay.
Absolutely fine. I guess Cloudflare would be certainly happier if you had an Enterprise plan with each domain but there is no issue using the free plan.
