DNSPeek: Inspect DNS configuration and resolver behavior.
Which DNS servers is my Mac using, and do they respond?
The problem
Pages hang or a domain will not resolve. Which DNS servers is your Mac actually asking, and are they answering?
The solution
DNSPeek will show the active interface, resolver configuration and DNS servers, and measure lookup latency when you ask. It is read-only and never changes DNS settings.
Planned features
- Active interface and DNS servers
- Resolver configuration and search domains
- Lookup latency measured on request
- Read-only: never changes DNS settings
How it works
- Open DNSPeek from the launcher.
- Read your resolver configuration.
- Run a lookup to measure latency.
Installation
DNSPeek is not released yet. It is already listed in MacPeek's Manage utilities screen as Coming soon; when it ships it will appear there to switch on, with no separate download. Install MacPeek to get the launcher and PortPeek, DisplayPeek, USBPeek, SleepPeek, FileLockPeek, ProcessPeek, DiskPeek and EnvPeek today.
Privacy
What DNSPeek will read:
- System resolver configuration; lookups only when you run a check
Access it needs: None.
Nothing about your Mac is sent to any server, and there is no account and no telemetry. DNSPeek will make network requests only when you ask it to run a check. Read the full privacy statement.

Want DNSPeek? It is on the roadmap. PortPeek, DisplayPeek, USBPeek, SleepPeek, FileLockPeek, ProcessPeek, DiskPeek and EnvPeek are built into the app today, and DNSPeek will arrive in the same app.
