Bulk change master nameserver?
I have several domains as secondary with Linode (I run the master DNS). How can I change that master all at once? It'd be kind of a pain to do each one individually…
At the moment, bulk editing of your records is not a feature we offer within the Cloud Manager. This would make a great feature for users with a high number of domains though, and so I will be sure to include your feedback into our tracking system for review.
You will need to edit each domain's record individually using the instructions in the following guide for your current needs.

However, it may be possible with some clever scripting using our API to edit those fields you are looking to change. You would need to write a script to edit the proper fields for your domains.
