I am learning on the field and the ping command is cool. Most of this of course depends on the devices being in use. I am interested in this thread, hopefully someone can help. There are 4 types of arp message: arp request, arp reply, rarp request, rarp reply. So, that being said, is it possible to manually send a rarp request? Sort of a arp based ping? There is arping, but we need rarping Of course, I understand that I can't arp outside my default gateway, but if there is a rarp request, how is it used inside the local network?
Thanks to whatever guru can explain what we're missing. My instance where I found this useful was after updating the firmware on a switch remotely via TFTP, the IP of the switch would change making pinging redundant, obviously. Trying a network scan over Spiceworks or rescanning the single device would not update the IP and I needed an alternate way to find it.
This method worked perfectly. Thank you. Hopefully this helps those trying to understand the purpose of this practice and how it was in-fact useful. I understand the issues in attempting to use a MAC address to locate a device from outside of its local network. The router is connected to Comcast with a Motorola SB modem. Comcast assigns a system wide dynamic IP.
There is no static IP. On initial setup, a WiFi connection is first established between the thermostat and the router. It is then possible to read or set thermostat values using Total Connect Web pages. Does anyone understand how this works with Total Connect? This post was extremely helpful, thanks itdownsouth : I used show interface to find MAC addresses on our switches reason for this is poor network documentation and mis-labeled switchports and wall jacks Tedious, but found 5 or 6 now seeing hexadecimal thoughts now though By the way, the reason this is working great for me is the lack of routers -- all switches, so if you have only one subnet like we do, this will do -- otherwise, you will probably need to login to the router or switch on the other side of the router to find MAC address tables on the other networks.
You may not be able to see them all on the local host, as far as arp -a on the local host, but looking up the arp or hosts tables on switches and routers could be a possible solution for those with multiple subnets. Use SuperScan to do a bulk ping of the entire network range. SuperScan 3 I recommend is a free tool by McAfee. It should be able to find most devices on the network. You can specify the range to scan and scan across subnets. I won't try to share all the features because quite frankly I don't know them all. I can tell you exactly how I designed it.
It's actually quite simple. Nothing is sent back to the unit. For a free tool, SolarWinds IP Address Tracker is extraordinary: not only does it allow users to manage up to IP addresses, but it automatically pushes alerts when IP address conflicts occur. Finally, its graphical user interface displays information in an intuitive and digestible format, highlighting notable events while remaining comprehensive in nature. For example, it shows a list of custom reports, the last 25 IPAM events, current conflicts, and ranked subnets by the percentage of available addresses used.
Widely hailed as one of the first and most popular free IP address scanners, Angry IP Scanner is open-source software, deployable across operating systems. Angry IP Scanner is easy to use and has an intuitive graphical user interface.
Further, it provides slightly more detail than the manual command-line method covered above. Given an IP address range, the tool displays all active IP addresses, hostname when applicable, ping response time, MAC address, and port count.
The functionalities it offers are fundamental and useful. Plus, anyone who writes Java is free to expand its abilities by creating their own plugins, though of course this would require a certain amount of buy-in.
Created by developer 10base-t Interactive and optimized for Mac, this app is admittedly limited; the free version only supports 6 devices. In this mode, network admins can see inactive devices that were once part of the network. This can help with troubleshooting in a variety of ways. Is this IP address now free for reallocation? Is this device supposed to be present, and something has gone wrong? IP Scanner takes some of the guesswork out of network fluctuations, making it possible to zero in on these questions and find answers.
By culling the display in this way, users can stay aware of which devices are new and may be on the network without authorization, receiving automatic alerts to potential threats.

In addition to all the SolarWinds IP Address Tracker features covered above, IPAM is a complete management solution, empowering admins to drill down into address conflicts, easily allocate IP addresses to subnets, and catalogue IP address usage history. These functions are crucial time-savers. This allows admins to temporarily remove the malfunctioning devices by remotely shutting down a port, thus facilitating network reliability and high performance while reconfiguring IP settings behind the conflict.
As regards address allocation, IPAM users can employ the automated Subnet Discovery Wizard and Subnet Allocation Wizard to sort IP addresses and form optimally sized subnets, maximizing performance while minimizing conflicts and wasted space. Better yet, IPAM features drag-and-drop and user-defined grouping, making portioning IP address space more convenient than ever before. One last notable feature here is that it offers priceless server synchronization. This makes it possible not merely to set alerts for conflicts and put out fires as they arise, but to prevent potentially expensive address conflicts to begin with.
This means customers can find available addresses, assign them, and update the DNS simultaneously, eliminating the possibility of misdirected traffic or duplication. This includes a slate of tools fulfilling the duties of an IP tracker or scanner, bolstered by myriad others in this holistic network management client. SolarWinds ETS performs automated network discovery, allowing it to undertake clear network visualization—a capability not found in most free tools. With the automated discovery, the toolset displays the network in its entirety, mapping out switch ports, relating MAC to IP addresses, and identifying equipment.
Not only does the Ping Sweep tool provide a quick rundown of which addresses are in use and which are available for assignment, but it also locates the DNS name corresponding to each IP address. It supplements this data with graphs charting device response time. The Subnet Calculator at once scans subnets; generates the proper masks, size, range, and broadcast address of both classful and classless subnets; and acts as an IP address tracker, continuously monitoring the addresses in use within each subnet.
This is an incredibly important function when re-architecting a network or trying to avoid downtime, as it gauges whether the network is due to run out of addresses before a verifiable shortage arrives. This helps ensure if a device is using an IP address, the network reaps the rewards of having allocated that address.
Coupled with the innumerable other amenities of SolarWinds ETS, its network scanning and IP address tracking features go even further in preventing network catastrophe, identifying problems early, ascertaining root causes, and executing quick resolutions. Its network device scanner tool automatically discovers network devices; beyond that, NPM creates visual displays that delineate the connections between devices — automatically populating maps that clarify network topology.
This is particularly helpful in the case of the dynamic IP address system, in which IP addresses in addition to device count and relationship are constantly in flux. In fact, with SolarWinds NPM, users can customize dynamic network maps that display accurate topology and device performance metrics, juxtaposing device scanning and network performance management so that admins can more easily architect high-performing networks and intervene on specific devices when necessary.

SolarWinds User Device Tracker UDT performs an IP address management role from a unique vantage point, looking more at the individual user in addition to network architecture. UDT is invaluable when it comes to granular network topology and equipment details. It automatically discovers and monitors layer 2 and layer 3 switches, and it constantly watches ports and switches, gauging response time, packet loss, CPU load, and memory utilization.
It sends alerts as switches approach their capacity.
