 # About ExpressRoute virtual network gateways
 
-To connect your Azure virtual network (VNet) and your on-premises network by using Azure ExpressRoute, you must first create a virtual network gateway. A virtual network gateway serves two purposes: to exchange IP routes between networks, and to route network traffic.

+## Hosted-On-Behalf-Of (HOBO) Public IP
+
+The Hosted-On-Behalf-Of (HOBO) Public IP feature simplifies ExpressRoute gateway deployment by allowing Microsoft to manage the required public IP address on your behalf. With HOBO, you no longer need to create or maintain a separate public IP resource for your gateway.
+
+**Key benefits:**
+
+- **Improved security:** The public IP is managed internally by Microsoft and isn't exposed to customers, reducing risks associated with open management ports.
+- **Reduced complexity:** Customers aren't required to provision or manage a public IP resource.
+- **Streamlined deployment:** The Azure portal and CLI no longer prompt for a public IP during gateway creation.
+
+**How it works:**  
+When you create an ExpressRoute gateway, Microsoft automatically provisions and manages the public IP address in a secure, backend subscription. This IP is encapsulated within the gateway resource, enabling Microsoft to enforce policies such as data rate limits and enhance auditability.
+
+**Availability:**  
+HOBO Public IP is currently in preview for ExpressRoute Virtual Network Gateways. It isn't available for Virtual WAN (vWAN) or Extended Zone deployments.

 You can also deploy ExpressRoute gateways in Azure availability zones. Physically and logically separating the gateways into availability zones helps protect your on-premises network connectivity to Azure from zone-level failures.
