IP Address shown on signed documents
When a Contact signs a PDF within the Nimbus system, their Public IP address attached to the device used to sign the document, will be included in the signing detail.
For your business, it would depend on the public IP address of the device used when signing the document. If your devices are behind a firewall, it would depend on your firewall settings, and it may be that all staff whose devices sit behind the firewall show as the same IP address.
