Do you know about any Linux tools to migrate records from existing nameserver to a new (self-hosted) nameserver? We have multiple domains and it will be pain to migrate all of them manually. Thanks!

With OVH as registrar, that would be as easy as just copying the DNS zone.

@kescherRant The problem is, we don't own any of these domains, so almost each one of them is from different registrar. We only provide services behind them - A records point to our servers. So everytime we migrate to another server (hopefully won't be happening often or never) we need to ask everyone to change the A record. The solution to this problem would be using our nameservers, so when server IP changes, clients don't have to do anything.

So we need to migrate these DNS records to our server before we will be able handle everything correctly.

@lamka02sk why not set up some domain you own and tell your clients to create a cname to your domain?

.

@ebrithil Well, that would work I guess, but what about other records as they are not allowed (this rule is not really enforced but still...)

"CNAME records can only exist as single records and can not be combined with any other resource record ( DNSSEC SIG, NXT, and KEY RR records excepted)"

// Edit: Sometimes this rule is enforced https://serverfault.com/questions/...

@lamka02sk yeah it would have to be a dedicated domain/subdomain.
