To comply with Amazon S3 requirements, bucket names:
* Can contain lowercase letters, numbers, periods (.), underscores (_), and dashes (-)
* Must start with a number or letter
* Must be between 3 and 255 characters long
* Must not be formatted as an IP address (e.g., 192.168.5.4)
To conform with DNS requirements, we recommend following these additional guidelines when creating buckets:
* Bucket names should not contain underscores (_)
* Bucket names should be between 3 and 63 characters long
* Bucket names should not end with a dash
* Bucket names cannot contain two, adjacent periods
* Bucket names cannot contain dashes next to periods (e.g., "my-.bucket.com" and "my.-bucket" are invalid)
