DNS Lookup helps during security assessments or pentesting labs where you need to inspect HTTP headers, verify SSL configuration, or test endpoint responses without exposing your source IP or installing verbose CLI tools.

Key features of DNS Lookup

Common use cases for DNS Lookup

Is the DNS Lookup safe and private?

What kind of output does the DNS Lookup produce?

Only where the task requires it (for example, looking up a DNS record). The interface and any parsing happen in your browser, and Toolblip doesn't log the queries you make.
Does the DNS Lookup make real network requests to the URLs I check?
Yes, where the diagnostic requires it. For HTTP header checks and DNS lookups, the tool makes real network requests from your browser. Toolblip does not log these requests. For operations that do not require network access, everything is handled client-side.
Can I use the DNS Lookup offline?
