In Windows 11, the 'Local Peer Discovery' option was introduced to restrict peer discovery to the local network. Currently the available options include: 0 = NAT, 1 = Subnet mask, and 2 = Local Peer Discovery. These options apply to both Download Modes LAN (1) and Group (2) and therefore means there's no peering between subnets. -If Group mode is configured, Delivery Optimization connects to locally discovered peers that are also part of the same Group (have the same Group ID). +If Group mode is configured, Delivery Optimization connects to locally discovered peers that are also part of the same Group (have the same Group ID) and prevents devices that aren't using the same Group ID from participating. In Windows 11, the Local Peer Discovery (DNS-SD) option can be configured via MDM or Group Policy. However, in Windows 10, this feature can be enabled by setting the `HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization\DORestrictPeerSelectionBy` value to **2**. +The default behaviors differ between Windows 10 and Windows 11.
