The Shadowserver Foundation

Accessible/Open IPP Server Scanning Project

If you are looking at this page, then more than likely, you noticed a scan coming from this server across your network and/or poking at your IPP service.

The Shadowserver Foundation is currently undertaking a project to search for publicly accessible devices that have an Internet Printing Protocol (IPP) server running. The goal of this project is to identify openly accessible systems that have IPP running and report them back to the network owners for remediation.

All IPP servers that we find have been incorporated into our reports and are being reported on a daily basis.

Methodology

We are querying all computers with routable IPv4 addresses that are not firewalled from the internet on port 631/tcp with the standard Get-Printer-Attributes command and capturing the response. We intend no harm, but if we are causing problems, please contact us at gro [tod] revfooreswodahs [ta] nacbarssnd

This scan was enabled as part of the European Union INEA CEF VARIoT project.

Blocklisting

To be removed from this set of scanning you will need to send an email to dnsscan [at] shadowserver [dot] org with the specific CIDR's that you would like to have removed. You will have to be the verifiable owner of these CIDR's and be able to prove that fact. Any address space that is blocklisted will be publicly available here: https://scan.shadowserver.org/ipp/exclude.html
