DNS Error

If the PTK displays an error for DNS lookups, this indicates that the network DNS is either being intercepted or is misconfigured. The PTKs conduct DNS A Record lookups to the gateway.ptk.rapid7.com host located at 18.222.54.19. If this is not the displayed IP address or the host lookup fails (ie returns NXRECORD), contact your networking team and ensure that a whitelist is put in place for the PTK host and the PTK subdomains.

Additionally, ensure that any domain categorizing network appliances allow accessing of the Rapid7 PTK hosts without a categorization block.

Custom DNS

If you would like to specify your own DNS, please reconfigure the device by following the steps in the Reconfigure Networking section.
