How this DNS lookup works

Single mode queries the full DNS record set for one domain. Multiple mode is optimized for speed: it checks the core records first, shows a compact summary table, then loads full details only for the row you open. Results are cached briefly so repeated checks stay snappy.

Frequently asked questions

Why can multiple mode be faster?

It checks the most useful record types first and avoids rendering full DNS dumps for every domain at once. That keeps queue work lighter and the Livewire response compact.

What should I do if a row shows an error?

An error row usually means the domain is invalid, currently unreachable, or has no records for the queried scope. You can still open the row to try a full lookup for more context.
