- New peer selection options: Currently the available options include: 0 = NAT, 1 = Subnet mask, and 2 = Local Peer Discovery. The subnet mask option applies to both Download Modes LAN (1) and Group (2).

- New peer selection options: Currently the available options include: 0 = None, 1 = Subnet mask, and 2 = Local Peer Discovery. The subnet mask option applies to both Download Modes LAN (1) and Group (2). If Group mode is set, Delivery Optimization will connect to locally discovered peers that are also part of the same Group (have the same Group ID)."
- Local Peer Discovery: a new option for **Restrict Peer Selection By** (in Group Policy) or **DORestrictPeerSelectionBy** (in MDM). This option restricts the discovery of local peers using the DNS-SD protocol. When you set Option 2, Delivery Optimization will restrict peer selection to peers that are locally discovered (using DNS-SD). If you also enabled Group mode, Delivery Optimization will connect to locally discovered peers that are also part of the same group (that is, those which have the same Group ID).
> [!NOTE]
> The Local Peer Discovery (DNS-SD) option can only be set via MDM delivered policies on Windows 11 builds. This feature can be enabled in supported Windows 10 builds by setting the `HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization\DORestrictPeerSelectionBy` value to **2**. For more information, see [Delivery Optimization reference](/windows/deployment/update/waas-delivery-optimization-reference).

In Windows client Enterprise, Professional, and Education editions, Delivery Optimization is enabled by default for peer-to-peer sharing on the local network (NAT). Specifically, all of the devices must be behind the same NAT, but you can configure it differently in Group Policy and mobile device management (MDM) solutions such as Microsoft Intune.
