'Why are these CIDR causing errors with Snowflake Network Policy?
Any ideas why the below IP addresses are saying they are invalid with Snowflake's Network Policy? It seems they support CIDR.

Solution 1:[1]
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..
https://fivetran.com/docs/getting-started/ips
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
