Any ideas why the below IP addresses are saying they are invalid with Snowflake's Network Policy? It seems they support CIDR. IP Addresses with issues

the first two are Tableau public addresses.

Host Name (Instance) Site Location IP Address or Range
prod-useast-a.online.tableau.com US East - Virginia 3.219.176.16/28
prod-useast-b.online.tableau.com US East - Virginia 3.219.176.16/28

The third is fivetran..

and the last is redshift.

But I suspect you know that.. it could be that they have a "block" block, to stop people foot gunning them selves.

I would ask a support question. because it should be valid

Using the classic console did the trick for us

Was a bug in snowflake, response from their team:

The behavior which you are seeing is failing from Snowsight. This is already identified and is currently under review.

Please make a note of the internal tracking number: SNOW-549872.

I am afraid that I do not have an ETA for the fix yet.

Edit on 2022/02/28: This issue in Snowsight is now fixed.
