- Excluded IP Addresses: The total number of IP addresses that are
currently excluded from assignment.
- Available IP Addresses: The total number of IP Addresses that are
currently available for assignment. This number is equal to the Total IP Addresses
- (Utilized IP Addresses + Excluded IP Addresses).
- Percentage Utilization: This value is equal to the (Utilized IP Addresses
/ Total IP Addresses ) * 100.
