The provided statement "Provider networks can be external networks by setting the external parameter to yes, and the shared parameter to no at creation. Provider networks that are not external have the external parameter set to yes, and the shared parameter also set to yes. External networks created by a user with administrator privileges requires a floating IP address pool."  appears to have some inconsistencies and could benefit from some clarification for accuracy and clarity. Here's a revised version:

"Provider networks can be designated as external networks by setting the 'external' parameter to 'yes' and the 'shared' parameter to 'no' during their creation. For provider networks that are not intended to be external, the 'external' parameter should be set to 'no,' and the 'shared' parameter can be set to 'yes.' It's important to note that external networks created by a user with administrator privileges typically require access to a floating IP address pool."

In this revision, the distinctions between external and non-external networks are more clearly articulated, and it's specified that external networks created by administrators often require access to a floating IP address pool.
