Determining IP addresses used on the network

[Laneyh]

Hi

My office has a smalll network set up. There are basically around 4 users a file server and webserver connected to the network.

There is also a cisco router and a netgear wireless router. I think the IP conflict may lie with
the wireless router

I have tried pinging the address which I thought the router had but it times out
Is there an easy way to determine the IP address of the router or better still any software I can run from my desktop to determine what IP address is being used by everything connected to the network ?

Thanks in advance

why do you have 2 routers? if it's the wireless piece that's important get an access point.

but seeing you already have one in place. check the following:

1) make sure that the netgear is connected to the network via the LAN ports only.
2) turn the DHCP off on the netgear router so it is not happily distributing the IP addresses just like your cisco router is probably doing.

you can try: www.cisco.com/go/networkassistant it will help you manage any Cisco devices but it should also give you a quick topology of your network but if the wireless router ping is timing out then so would an SNMP discovery ping.

If you do that (convert the Netgear to a simple AP/switch) you have to change its IP to one in the Cisco's subnet.

Using ipconfig from the command line on each wired machine will give you the ip address used on that machine, or as an alternate, network connections, right click the connection and properties will bring up the services and protocols. right click the TCPIP and properties will give the address.
Assuming the router is assigning addresses all wired machines will be given adjacient numbers.

Setup for the routers is normally using a browser to the command port, so if you have an address conflict you will need to pull the wireless router and one wired machine off the network for the duration of the setup.
