1002 cloud-init: Specify IP addresses and gateways for the corresponding interface.
1004 IP addresses use CIDR notation, gateways are optional but need an IP of the same type specified.
1006 The special string 'dhcp' can be used for IP addresses to use DHCP, in which case no explicit
1007 gateway should be provided.
1008 For IPv6 the special string 'auto' can be used to use stateless autoconfiguration. This requires
1009 cloud-init 19.4 or newer.
1011 If cloud-init is enabled and neither an IPv4 nor an IPv6 address is specified, it defaults to using
