Maximum IP addresses per network interface - Amazon Elastic Compute Cloud

Maximum IP addresses per network interface

Each instance type supports a maximum number of network interfaces, maximum number of private IPv4 addresses per network interface, and maximum number of IPv6 addresses per network interface. The limit for IPv6 addresses is separate from the limit for private IPv4 addresses per network interface. Note that all instance types support IPv6 addressing except for the following: C1, M1, M2, M3, and T1.

Available network interfaces

The Amazon EC2 Instance Types Guide provides the information about the network interfaces available for each instance type. For more information, see the following:

Console
To retrieve the maximum network interfaces

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. In the navigation pane, choose Instance Types.

  3. Add a filter to specify the instance type (Instance type=c5.12xlarge) or instance family (Instance family=c5).

  4. (Optional) Click the Preferences icon and then turn on Maximum number of network interfaces. This column indicates the maximum number of network interfaces for each instance type.

  5. (Optional) Select the instance type. On the Networking tab, find Maximum number of network interfaces.

AWS CLI
To retrieve the maximum network interfaces

You can use the describe-instance-types command to display information about an instance type, such as its supported network interfaces and IP addresses per interface. The following example displays this information for all C8i instances.

{ echo -e "InstanceType\tMaximumNetworkInterfaces\tIpv4AddressesPerInterface"; \
aws ec2 describe-instance-types \
    --filters "Name=instance-type,Values=c8i.*" \
    --query 'InstanceTypes[*].[InstanceType, NetworkInfo.MaximumNetworkInterfaces, NetworkInfo.Ipv4AddressesPerInterface]' \
    --output text | sort -k2 -n; } | column -t

The following is example output.

InstanceType    MaximumNetworkInterfaces  Ipv4AddressesPerInterface
c8i.large       3                         20
c8i.2xlarge     4                         30
c8i.xlarge      4                         30
c8i.4xlarge     8                         50
c8i.8xlarge     10                        50
c8i.12xlarge    12                        50
c8i.16xlarge    16                        64
c8i.24xlarge    16                        64
c8i.32xlarge    24                        64
c8i.48xlarge    24                        64
c8i.96xlarge    24                        64
c8i.metal-48xl  24                        64
c8i.metal-96xl  24                        64
PowerShell
To retrieve the maximum network interfaces

You can use the Get-EC2InstanceType PowerShell command to display information about an instance type, such as its supported network interfaces and IP addresses per interface. The following example displays this information for all C8i instances.

Get-EC2InstanceType -Filter @{Name="instance-type"; Values="c8i.*"} |
Select-Object `
    InstanceType,
    @{Name='MaximumNetworkInterfaces'; Expression={$_.NetworkInfo.MaximumNetworkInterfaces}},
    @{Name='Ipv4AddressesPerInterface'; Expression={$_.NetworkInfo.Ipv4AddressesPerInterface}} |
Sort-Object MaximumNetworkInterfaces |
Format-Table -AutoSize

The following is example output.
