[dns-operations] using different DNS providers together

The providers can not intermeddle your choice. When a domain name is registered in many providers, they allow users to provide some name servers including theirs and other providers' NSs.  The records of name servers are transferred to tld name servers of the name. Recursors request some type of the name from tld NSs before all records are responded to recursors.  And they pick one NS of the name servers listed to continue to request what they like so that the authority service providers cannot do something.

The majority of the providers listed do not support being a DNS
"secondary" using A/IXFR.
They all expect you to use their own custom DNS management tools for
managing the domain and expect that you only have it hosted with them,
I'm not even sure some of the providers would allow you to create
additional NS records so yes there could be problems in that the glue
would not match the NS returned by one of the providers, so it would
appear that some of the NS are stealth.
