Network IP Address list

ShawnGray asked
Last Modified: 2014-05-14
In w2k8 r2 I have a list of ip addresses assigned by my DHCP server.
Is it possible to get a similar list showing static IPs (ie all devices and their IPs)?

There is no definitive way to do this. Almost all modern networks have switches instead of hubs and the switched fabric means that there is a good likelihood that few machines (if any) see all traffic and even when a device broadcasts, machines won't store that information indefinitely. ARP tables are flushed regularly to avoid stale records.

Tools like nmap can help by trying to query devices, but it is a best effort approach. It doesn't gaurantee that you are seeing every device on a local broadcast domain. The only real way to know what is on a network is thorough documentation and standard security practices to prevent rogue devices.

Although Cliff is technically right, I insist, nmap does a pretty good job, depending on what you need. Why don't you give it a try and let us know?
That's why a program like Look@LAN would help - it will reach out and tell you, based on a IP-range search (e.g. what IP addresses are used and which ones aren't.  It will also give you OS information and tell you the type of device that it is.  It's pretty accurate overall for a quick snapshot of your network.
