Network Interface
The AWS::EC2::NetworkInterface resource creates network interface
Properties
The number of IPv4 prefixes to assign to a network interface. When you specify a number of IPv4 prefixes, Amazon EC2 selects these prefixes from your existing subnet CIDR reservations, if available, or from free spaces in the subnet. By default, these will be /28 prefixes. You can't specify a count of IPv4 prefixes if you've specified one of the following: specific IPv4 prefixes, specific private IPv4 addresses, or a count of private IPv4 addresses.
Assigns a list of IPv4 prefixes to the network interface. If you want EC2 to automatically assign IPv4 prefixes, use the Ipv4PrefixCount property and do not specify this property. Presently, only /28 prefixes are supported. You can't specify IPv4 prefixes if you've specified one of the following: a count of IPv4 prefixes, specific private IPv4 addresses, or a count of private IPv4 addresses.
The number of IPv6 prefixes to assign to a network interface. When you specify a number of IPv6 prefixes, Amazon EC2 selects these prefixes from your existing subnet CIDR reservations, if available, or from free spaces in the subnet. By default, these will be /80 prefixes. You can't specify a count of IPv6 prefixes if you've specified one of the following: specific IPv6 prefixes, specific IPv6 addresses, or a count of IPv6 addresses.
Assigns a list of IPv6 prefixes to the network interface. If you want EC2 to automatically assign IPv6 prefixes, use the Ipv6PrefixCount property and do not specify this property. Presently, only /80 prefixes are supported. You can't specify IPv6 prefixes if you've specified one of the following: a count of IPv6 prefixes, specific IPv6 addresses, or a count of IPv6 addresses.
Assigns a list of private IP addresses to the network interface. You can specify a primary private IP address by setting the value of the Primary property to true in the PrivateIpAddressSpecification property. If you want EC2 to automatically assign private IP addresses, use the SecondaryPrivateIpAddressCount property and do not specify this property.
The number of secondary private IPv4 addresses to assign to a network interface. When you specify a number of secondary IPv4 addresses, Amazon EC2 selects these IP addresses within the subnet's IPv4 CIDR range. You can't specify this option and specify more than one private IP address using privateIpAddresses
