InformationThe Peer Name Resolution Protocol (PNRP) allows for distributed resolution of a name to an IPv6 address and port number. The protocol operates in the context of clouds. A cloud is a set of peer computers that can communicate with each other by using the same IPv6 scope.
Peer-to-Peer protocols allow for applications in the areas of RTC, collaboration, content distribution and distributed processing.
The recommended state for this setting is: Enabled.
This setting enhances the security of the environment and reduces the overall risk exposure related to peer-to-peer networking.
