# Subnet

A subnet is a range of IP addresses in a cloud network. Addresses from this range will be assigned to one or multiple servers in the Metal Cloud. Only IPv4 is supported.

#### Create a subnet

| <ul><li>A CIDR range is allocated automatically. It will be held for 60 seconds and be updated to the new one after that on the screen.</li><li>A network ACL is required to create with a subnet. By default, <strong>only outbound traffic</strong> from the Bare Metal GPU server to the internet <strong>will be allowed</strong>.</li><li><strong>The quota of subnet is equal to the quota of the Bare Metal GPU server.</strong></li></ul> |
