List all static IP addresses on network

Easy question for somebody:  How do I get a list of all the static IP addresses on our network? We are using a SonicWall as the DHCP server but nothing listed there.

It's a bit harder than you would expect it to be.  Unless they were configured within the Sonicwall and the Devices. But most of the time they are just setup on the devices and not the sonicwall.

Look@LAN is a program that should be able to help you with this.  It should list the Devices that have a manual network configuration(ie. Static).
At the command prompt on any pc use "arp -a"

This will show you both.
Run an IP scan on the network, any active IP's that are returned and not listed in the dhcp client list of the router must be statically assigned

see below link same discussion was done and a lot of resolution provided there. you can select any of them and use it.
arp will reflect all systems that accessed the network within the ARP expiration period.
ping is not a valid check when a firewall might prevent ping packets from being received/responded to.

It is often preferred to use a windows DHCP/DNS on a network with windows systems as it provides the flexibility to use the various resources to compare and collect the data.
You can query the AD for all computer objects that are active, you then check the DHCP to see which of the computer objects are reflected as being issued an IP by the DHCP server (this will include both dynamic and DHCP assigned statics)
Then you will check the DNS server to see which hosts have registered and the IPs they registered with.

Actually, I found a free app on CNET called Advanced IP Scanner on CNET.  It is really great and showed me all the printers, IP phones, everything.
