A host without SDN simply shows that none is configured.\n- ### Network templates\n\nA template sets the zone type (simple, VLAN, QinQ, VXLAN or EVPN), a supernet, the subnet size per project, the gateway, SNAT and DHCP. Saving a template changes nothing on Proxmox.\n- ### A VNet per project\n\nA new project gets its own VNet and the next free subnet from its template, created and applied in the background, with a status and a Retry button.\n- ### IPs assigned automatically\n\nEvery project network has its own IP pool, so new guests get the next free address, or DHCP hands one out.\n- ### DHCP that respects the node\n\nWith DHCP on, the agent installs and enables dnsmasq for the zone only if it is missing. If a dnsmasq already runs on the node, it is left alone and the project uses static IPs."},{"heading":"Why not just use the Proxmox web UI?","content":"Proxmox VE runs the virtualization.
