## Capabilities and processing

Enter a name or paste NS records (dig or zone file lines). A name is sent to our server, which asks a public resolver; pasted records are read in your browser.

The nameservers at the zone apex, each with its provider, checked for count and for more than one provider. A name inside a zone has no NS records of its own; the page offers to look up the zone.

## Example workflow

The sample domain is served by two providers, as after an unfinished migration.

## Limits and interpretation

Two providers can be deliberate secondary DNS. Nothing is stored.
