In order to organize and cleanup the dhcpd.conf file, include statements were utilized to organize reservations by Vlan (i.e. include "/etc/dhcpd.v220.res" for Vlan 220). All of the reservation information was then move to the dhcpd.vXXX.res files. When an IP address is selected to become a reserved IP address IPAM puts the updated information in the dhcpd.conf file. This is fine if you have a small environment, if you have a large environment you will eventually clutter your dhcpd.conf making it messy and hard to decipher. It would be nice to have the ability to select the file that you would like for the reservation IP address update information to be directed to. It would also be nice if the information was appended to the bottom of the selected file so that you could keep things in sequential order if you assigned you reservation IP addresses in an descending order.
Along with the ability to direct the output of the IP address reservations update it would enhance IPAM's usefulness to give the ability to include all of the possible per-host reservation options available. They could be null by default but available for use if needed when making an IP address reservation update.
