I wonder if something like that is possible. To have one domain, handled by 2 DNS servers, master zones.
For example, I have the domain, domain.com on a registrar and I want to make ns1.domain.com and ns2.domain.com. I want to have ns1.domain.com on VPS1 and ns2.domain.com on VPS2, both having a BIND installed, pointing to VPS3, where the website is hosted.
Can be done, like that ? To have 2 master zones for same domain, with one ns each, on different IP's, both pointing to another one.
