phpIP Management script changes

This project requires some customisation done to the script phpIP Management - [login to view URL] We essentially need an easy to follow and use way of managing a range of Class C's and other Ip ranges from various locations, with PTR lookup and resolution checks and assignment of IP's and IP ranges to various hardware types Required changes are: - Addition of field to system to show manually entered PTR record for each IP address - Addition of fields on IP range display page to show manually entered PTR record and returned PTR record (instead of the javascripthover currently used) and a comparison of the 2 results to display a red X or green tick depending on if they match or not - Ability to assign IP's to a specific device, server or similiar with ability to display IP's assigned to that server specifically in a similar fashion to the current Class display page - add fields to enter and display gateway IP for a specific IP or range of IP's and add fields to enter and display DNS servers for the IP range Ability to filter thru IP ranges and hardware in a topographical manner ie router >> Switch >> Servers ideally we would like to be able to integrate this with out existing cacti and nagios installations and data can be pulled from them if required if someone has a better solution to suggest than phpIP then we would be open to that.
