Turn off PNRP cloud creation

Description:

This policy setting enables or disables PNRP cloud creation.

PNRP is a distributed name resolution protocol allowing Internet hosts to publish peer names with a corresponding Internet Protocol version 6 (IPv6) address. Other hosts can then resolve the name, retrieve the corresponding address, and establish peer-to-peer (P2P) connections. The PNRP cloud is a group of connected PNRP nodes, in which connections exist between peers so that a node in the PNRP cloud can resolve names published by other nodes.

PNRP creates a global cloud if the computer has a global IPv6 address, but creates a site-local cloud if the computer has a site-local address.

If you enable this policy setting, PNRP does not create a cloud, and applications cannot use this cloud to publish or resolve names regardless of whether the computer has an IPv6 address that matches the cloud scope.

If you disable or do not configure this policy setting, all PNRP clouds are turned on by default, and PNRP creates a cloud if the computer has an IPv6 address compatible with the cloud’s scope.
