++
+IP addresses use CIDR notation, gateways are optional but need an IP of the same type specified.
++
+The special string 'dhcp' can be used for IP addresses to use DHCP, in which case no explicit
+gateway should be provided.
+For IPv6 the special string 'auto' can be used to use stateless autoconfiguration. This requires
+cloud-init 19.4 or newer.
++
+If cloud-init is enabled and neither an IPv4 nor an IPv6 address is specified, it defaults to using
+dhcp on IPv4.
