+Subnets
+~~~~~~~
+
+A Subnet allow to define an ip network (ipv4 or ipv6).
+
+
+Subnet properties are:
+
+* ID: a cidr network address. Ex: 10.0.0.0/8
+
+* Gateway: ip address for the default gateway of the network. 
+           On layer3 vnets (simple/evpn plugins), it'll be deployed on the vnet.

+* Snat: Enable Snat for layer3 vnets (simple/evpn plugins) for this subnet.

+* Ipam: Optional, if you want to use an ipam tool for this subnet.

+Ipams
+~~~~~
+IPAM (IP address management) tools, are used to manage/assign ips on your devices on the network.
+It can be used to find free ip address when you create a vm/ct for example (not yet implemented).
