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