Description:

dhcpstatus 0.0.5

dhcpstatus is a pure python implementation of DHCPSTATUS (http://dhcpstatus.sourceforge.net/),
implementing most of its functionalities.

With subnet status operation, dhcpstatus will return IP details for each subnet. It will provide:

IP range defined for the subnet
Total number of IPs defined for use
Count of free IPs in the subnet
Count of used IPs in the subnet
IPs leased out from each subnet
MAC address of the host the IP is leased
Hostname of the machine DHCP IP is leased to

Usage dhcpstatus command : dhcpstatus_subnet
dhcpstatus installation also comes with command style entry point dhcpstatus_subnet. You can run dhcpstatus
in standalone cli mode using binary dhcpstatus_subnet:
$ dhcpstatus_subnet /path/to/dhcp_subnet.conf /path/to/dhcpd.lease

dhcpstatus API usage
from dhcpstatus import *
import pprint

d=DHCPStatus('/path/to/dhcp_subnet.conf ', ' /path/to/dhcpd.lease')
status = d.subnet_status()

pprint.pprint(status)
OR
import dhcpstatus
import pprint

d=dhcpstatus.DHCPStatus('/path/to/dhcp_subnet.conf ', ' /path/to/dhcpd.lease')
status = d.subnet_status()

pprint.pprint(status)
And you can see output as:
