+Subnets
+~~~~~~~
+
+A Subnet allow to define an ip network (ipv4 or ipv6).
+
+It can be used to restrict ip addresses you can define on a specific vnet,
+assign routes/gateway on vnet in layer3 zones,
+enable snat on vnet in layer 3 zones,
+auto assign ips on vm/ct through ipam plugin && dns registration through dns plugins.
+
+
+Subnet properties are:
+
+* ID: a cidr network address. Ex: 10.0.0.0/8
+
+* Vnet: an associated vnet
+
+* Gateway: ip address for the default gateway of the network. 
+           On layer3 zones (simple/evpn plugins), it'll be deployed on the vnet.
+           
+* Snat: Optional, Enable Snat for layer3 zones (simple/evpn plugins) for this subnet.
+        The subnet source ip will be natted to server outgoing interface/ip.
+        On evpn zone, it's done only on evpn gateway-nodes.
+
+* Ipam: Optional, if you want to use an ipam tool for this subnet.
+        The subnet will be auto created in the ipam tool.
+
+* Dns: Optional, dns api server for forward zone.
+
+* Dnszone: Optional, dns domain name. Use to register hostname like  <hostname>.<domain>
+           The dns zone need to be already existing in dns server.
+
+* Dnszoneprefix: Optional, add a prefix to domain, like <hostname>.prefix.<domain>
+
+* ReverseDns: Optional, reverse dns api server for reverse zone.
+
+* ReverseDnsZone: Optional, reverse dns domaine name. ex: 0.168.192.in-addr.arpa
+                  The dns reverse zone need to be already existing in dns server.

+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).
