Hello,

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](http://ns1.mail.mybox.de) and [ns2.mail.mybox.de](http://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/](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?

Some top level domains require you to run at least one secondary nameserver which must be hosted on a different server / IP address than the primary nameserver. You can either set up your own: [Guide: How to setup NSD as a secondary nameserver for Mail-in-a-Box](https://discourse.mailinabox.email/t/guide-how-to-setup-nsd-as-a-secondary-nameserver-for-mail-in-a-box/9039/)

…or you can use a DNS provider that offers secondary name servers as a service, such as [Setting up Secondary DNS for Mail-in-a-Box - AnyDomain LLC](https://anydomain.net/setting-up-secondary-dns-for-mail-in-a-box/).
