nat64 address-group
Function
The nat64 address-group command creates a NAT64 address pool or enters the view of a specified NAT64 address pool.
The undo nat64 address-group command deletes a NAT64 address pool.
No NAT64 address pool is configured by default.
This command is supported only on the NetEngine 8000 F1A.

| start-address |
Specifies a start IP address in a public address pool. |
The value is in dotted decimal notation. |
| mask mask-length |
Specifies the mask length of public IP addresses. |
The value is an integer ranging from 1 to 32. |

Usage Guidelines
Usage Scenario
An IPv4 address pool can be configured in a NAT64 instance. To allow an IPv6 user to access an IPv4 network through a NAT64 device, the device translates the source IPv6 address in user packets into an IPv4 address from the IPv4 address pool and forwards the user packets to the IPv4 network.
The address pool supports the PAT and No-PAT modes. By default, the PAT mode is used. In PAT mode, the IPv6 addresses of multiple users can be translated into one IPv4 address. In No-PAT mode, a single IPv4 address is assigned to each IPv6 user.Follow-up Procedure
If you do not specify an address range for a NAT64 address pool created using the nat64 address-group command, run the section command in the NAT64 address pool view to configure an address range.
