Popular workflow

Check a website before launch

Start with availability, then verify DNS, certificate and page metadata.

A result you can act on

Checks run from the NexIP server and reflect its network path.

Inputs are normalized and private targets remain protected by the backend.

Saved results can be exported or shared when the current plan allows it.

Need continuous control?

Monitoring repeats checks on schedule and records incidents instead of requiring manual runs.

Questions about checks

Do checks change the target website?

No. Diagnostic tools read public technical data and do not modify the target.

Why can another service show a different result?

DNS cache, network route, region and check time can affect the response.
