Frequently asked questions
What is secondary DNS?
A secondary nameserver serves a copy of the records from your primary DNS server. Once both are listed in your domain’s delegation, the secondary can keep answering queries if the primary is unavailable.
How do I get started?
Create an account, verify your email, and request a zone in the client area. After we confirm you control the domain, authorize zone transfers on your primary server. Check that the secondary is answering correctly before adding it to your domain’s delegation.
Will it work with my current DNS provider?
Your primary DNS provider must support outgoing zone transfers (AXFR) to an external secondary nameserver. Check with your provider if you’re unsure whether your plan supports this.
Where do I edit my DNS records?
Edit records at your primary DNS provider. BackupSecDNS receives updates through zone transfers. You can view the transferred records and check sync status in the client area.
When does my free trial start?
If you select the 14-day free trial at signup, it starts when you verify your email address.
How long does a paid plan last?
Each confirmed one-time payment adds one calendar month of client access. You can choose a plan from the client area.
How do I reset my password?
Use the password reset option on the client sign-in page. The reset link expires after 30 minutes.
