Network Monitoring Tools

OIT Networking & Monitoring Services uses a number of systems to monitor the campus data network.

Rover: The Network Status Monitor
We monitor the reachability of campus network components with Rover. You can view the live Rover display, or review the event logs.

Use this to trace the current path from www.net.princeton.edu to another Internet host you specify.

Hardware Address Last in IP ARP Data (HALIAD)
The Hardware Address Last in IP ARP Data (HALIAD) facility allows you to search recent IP ARP data collected by OIT. You may search for a hardware address to learn the most-recent date on which that address appeared.

Other Tools

DNS Lookup
A tool to lookup a hostname or IP address in the Internet's Domain Name System. (This is not the same as looking up an entry in the Princeton University Host Database.) The tool is only available to on-campus clients.

Identify My Computer
A tool to display the Princeton University Host Database entry corresponding to the IP address your device is presently using.

This tool will soon be retired .

Categorize IP Address
Given an IP address on the Princeton University campus network, this tool will categorize the IP address into one of several broad categories; e.g. OIT Static IP Address, OIT Mobile IP Address, Temporary Visitor Wireless Network Access (TVWNA) IP Address, etc.

This tool will soon be retired .

Software for Network Administrators
A small collection of software developed or modified by OIT Networking & Monitoring Services, of possible use to other network administrators.
