I have a MIAB server at Contabo and set up a new one with more power and a new IP. When I originally set up my MIAB servers, it was possible to assign the same IP to both name servers (ns1.mail.mybox.de and ns2.mail.mybox.de), but this is no longer possible, at least not with this de-Domains. The following error message then appears:
ERROR: 53300102912 Nameserver error [ERROR: 107 Insufficient diversity of nameserver’ s IPaddresses (expected, found) (1, 0)]
But it’s also not possible to set only one Nameserver.
Denic has a Nameserver testing website: https://nast.denic.de/
Now I mad all DNS settings manually like from MIAB recommended and everything is working, but the way MIAB works as NS is much better, is there a way to get this running?
