Open QOTD Report

LAST UPDATED: 2022-08-29

This report identifies hosts that have the Quote of the Day (QOTD) service running and accessible on the Internet.

These services have the potential to be used in amplification attacks by criminals that wish to perform denial of service attacks. The service is tested by sending a UDP packet containing a single carriage return to UDP port 17.

For more details behind the scan methodology and a daily update of global QOTD scan statistics please visit our dedicated QOTD scan page.
