 By providing the VPN IPs/masks, you are configuring both: **the VPN internal networks and VPN server IPs**. Every gateway will bind to these addresses and Defguard will also generate and assign IP addresses for devices in this location from these networks.
 
+{% hint style="warning" %}
+Defguard assigns IP addresses to clients by sequentially scanning each defined subnet and selecting the first available address. If no free address is found in any of the configured networks, the client will not receive an IP assignment. In such cases, you’ll need to adjust the network configuration - such as expanding the address pool by decreasing the netmask - to accommodate additional clients.
+{% endhint %}
+
 This field can contain multiple IP addresses (both IPv4 and IPv6), separated by a comma (e.g. `10.10.20.1/24,fc00::abcd:0:1/96`).
 
+{% hint style="info" %}
+## Dual-stack VPN networks
+
+Defguard supports dual-stack VPN networks, allowing simultaneous assignment of both IPv4 and IPv6 addresses to clients. Each VPN network can include multiple IPv4 and IPv6 subnets, and connected clients will automatically receive one address from each defined subnet. This enables seamless communication over both IP versions within a single VPN session.
