Include IPv6 to the Basic Authentication in the Cloud Portal

[jonroberts24]

We recently encountered an issue when attempting to allow external IP addresses to view the DEV and STAGING versions of our Umbraco Cloud hosted website. Note: We did not want to add users to the backoffice of the CMS to access these sites - so users will not have a login account at this point.)

We discovered that if you have an IPv6 address, that you will not be able to access the website.

External => Azure (Works) via Basic Auth
Azure => Umbraco (Fails) via Umbraco Identity

From the logs it was determined that when you switch off Basic Authentication the IP addresses reaching the website are in fact Cloud Flare IP addresses and not your external IP address (v4 or v6).

If a user does not have an Umbraco account, which by all means isn't necessary then at the moment they have to go through two layers of authentication - BASIC and UMBRACO IDENTITY. It seems as though UMBRACO IDENITY is the one with the issue here.

Request:
Please make it possible so that admins can add IPv6 address to the whitelist, as I'm sure this is going to become a greater issue in the future due to the exhaustion of Ipv4 addresses.
