Feature #39478: mgr/dashboard: new RGW workflows & RGW enhancements
mgr/dashboard: Bucket names cannot be formatted as IP address.
as documented here https://docs.ceph.com/docs/master/radosgw/s3/bucketops/ a bucket name should follow some specific rules.
I found out that it's possible to enter an IP address as a bucket name in the dashboard and the input is valid but the bucket won't be created.
I think this should be catched such as all the other restrictions.
