Licensing Requirements and Limitations for IPv6 DNS

Involved Network Elements

Other network elements are not required.

Licensing Requirements

The IPv6 function must be enabled for the IPv6 DNS function. The IPv6 function is controlled by a license. By default, the IPv6 function is disabled on a new device. To use the IPv6 function, apply for and purchase the license from the device supplier.

For details about how to apply for a license, see Obtaining Licenses in the S7700 and S9700 Series Switches License Usage Guide.

Feature Limitations

• A switch only supports the IPv6 DNS client function.

• When static IPv6 DNS entries are configured, each domain name can map a maximum of eight IPv6 addresses.

• When dynamic DNS is configured, a maximum of six DNS server IP addresses (shared by IPv4 and IPv6) can be configured on the switch.
