Original GitHub issue: https://github.com/netbirdio/netbird/issues/4266

Describe the problem

Setting extra dns labels is only possible via netbird up, which as far as I understand will require creating new setup key, and will lead to peer IP address change, reconnect with downtime, etc.

To Reproduce

N/A

Expected behavior

DNS labels can be updated dynamically via dashboard

Are you using NetBird Cloud?

Self-hosted

NetBird version

0.51.2

Is any other VPN software installed?

No

Debug output

N/A

Screenshots

N/A

Additional context

N/A

Have you tried these troubleshooting steps?

Reviewed client troubleshooting (if applicable)
Checked for newer NetBird versions
Searched for similar issues on GitHub (including closed ones)
Restarted the NetBird client
Disabled other VPN software
Checked firewall settings

@gza commented on GitHub (Oct 1, 2025):

Also:

On big setup with multiple teams, granting to a setup key the right to set any DNS label is a security issue:
- By mistake or maliciously, one can get the traffic that was supposed to be sent to another service.
- I would recommend in the "Setup Keys" UI to allow to set a kind of wildcard/regexp to limit which DNS label can be set later by the key user.
On non-Kube environment, the deployment of a new service with a new DNS label requires to change the key and cut the VPN for a moment.

This is solved as of Management v0.66.4 and Dashboard v2.34.2

Permission to set extra DNS labels from peer side is now configurable at the time of setup key creation
New DNS Zones feature allows to set custom dns labels post-up from dashboard

I will close this issue

Just tried the latest version, and it doesn't seem to work. The UI shows the address without the second part, meaning that 'db1.europe.acme.com' will become 'db1.acme.com,' completely removing the second part of the subdomain. Key has DNS Label enabled.
