++ Prefixes for network interfaces are limited to IPv6 addresses and private IPv4 addresses\.
 + The maximum number of IP addresses that you can assign to a network interface depends on the instance type\. Each prefix that you assign to a network interface counts as one IP address\. For example, a `c5.large` instance has a limit of `10` IPv4 addresses per network interface\. Each network interface for this instance has a primary IPv4 address\. If a network interface has no secondary IPv4 addresses, you can assign up to 9 prefixes to the network interface\. For each additional IPv4 address that you assign to a network interface, you can assign one less prefix to the network interface\.
