966 cloud-init: Specify IP addresses and gateways for the corresponding interface.
968 IP addresses use CIDR notation, gateways are optional but need an IP of the same type specified.
970 The special string 'dhcp' can be used for IP addresses to use DHCP, in which case no explicit
971 gateway should be provided.
972 For IPv6 the special string 'auto' can be used to use stateless autoconfiguration.
974 If cloud-init is enabled and neither an IPv4 nor an IPv6 address is specified, it defaults to using
