## Symptoms

- * The administrator cannot determine the number of currently leased IP addresses from a specific Dynamic Host Configuration Protocol (DHCP) pool (examples: 10.5.0.0/20, 10.5.0.1 - 10.5.15.254) on a Check Point Gaia DHCP Server.

* Existing methods, such as commands from [sk104417](https://support.checkpoint.com/results/sk/sk104417), produce excessively large and unusable output for large subnets, and do not output a count of active DHCP leases.

* The `dhcpd.leases` file contains multiple entries for the same IP address, which results in inaccurate counts due to duplication.

## Cause

The Gaia DHCP server stores multiple entries for the same IP address in the `dhcpd.leases` file, including historical and duplicate records. Because of this, simple search or count operations overestimate the number of currently active leases. No built-in Gaia command exists to return the number of unique active leases for a specific subnet pool.
