IPv6 Support for upcoming Federal Mandate

We have regulatory obligations from our federal customers to offer IPv6 on our domains. 

The requirement is later this summer.

This is in accordance with the federal mandate linked here: https://www.whitehouse.gov/wp-content/uploads/2020/11/M-21-07.pdf
 

Please VOTE this up (and add a comment) if you will also be affected by the lack of Zendesk over IPv6. 

Currently, the Zendesk Network team says only IPv4 addresses are supported.
