We are working on feature realignment for Secondary DNS. Since it’s recently been migrated to paid-only, some options may still refer to requiring a paid account. Some of the paid vs. free features are are in the process of reevaluating are: TSIG support, master server settings, and zone file commands.
UPDATE:
- DNS TSIG key support for zone transfers are now available on Basic level accounts.
- A second master server is now allowed on Basic level accounts.
These features previously required a paid account of Personal or higher and were not available on free accounts. Since all Secondary DNS use now requires a paid account, these features have been realigned to an account level of Basic or higher.
