Hurricane Electric support a hidden primary as part of their free DNS nameserver service (do you actually want to expose your primary when someone else can handle the traffic?)

		Yup, but it's a bit of a dance for bootstrapping, since they require you to already have delegated to them, but some TLDs require all NSes to be in sync and answer for the domain before delegating…

Do most of them let you add an NS record?

		And if they don't, you might consider switching to Cloudflare for DNS hosting.
