Lookup Multiple IP Address

Multiple addresses? Do you mean two computers with the same IP address or one PC with multiple (two or more) IP addresses...

Peter

I think he wants to scan the network and have a list of all machine names with IP addresses, so he can find out what machines are using the same IP addresses.
Am I right, jpchen?

Hi,
  Sorry, I don't want to know what machine using same IP address.
I want to know what machine have more than one IP Addresses and have a list.

Thanks!!

There is a shareware product called NetScanTools which will scan a range of IP addresses and perform a reverse lookup against DNS to find the names.  I use this tool all the time and it is perfect for what you are trying to do.  The results can be saved in a text file and you can perform a search to find duplicates.  Contact details are listed here:

Hi,
  Thanks for respond.
  I tried this tool but it is not I want.
  I have IP address "199.233.129.252" and IP address "199.233.129.254" at same machine. But, the NetScan showed me the result is the two different DNS.  So, for this result I couldn't know these IP addresses is at same machine.

Thanks!!

Ben,
I think I know what you need.
Try NetXray from ngc, it's can sniffer, analyze and DISCOVER your network. I tried the discover option and I think it will do the trick. You can download a demo version at http://www.ngc.com/product_info/netxray/netxray.html, it can only capture 5 packets in tht analyzer mode, but the discover option is fully functional.
Give it a try...

Hi,
  I tried it and I don't get the right result.
  When I scan the IP address from 199.233.129.250 to 199.233.129.255. I only get one IP address is 199.233.129.254.
I know the 252 and 254 is at same machine.  Then, I only scan 199.233.129.252, I get the result.  Therefore I scan 199.233.129.254, the result for 252 is been place by 254.
I think this is a bug in this appliation.

Thanks!!

Are you using Windows NT 3.x or 4.x?
Why do you use two IP addresses on one NIC on the same subnet...

Do you have WINS server on your network?

Hi,
  I am using NT 4.0.
  Why I use two IP address on one machine?
  Because we don't want all machines become Web Server, I don't think this is a bad idea.  All ISP did this also.
  We didn't have WINS server on our network.
Thanks!!

Hi I have seen what you have discussed.

ok. you have a tool to find all aktive IP stations.
the next is to find multiple IP addresses on one machine. the only way is to use "nbtstat -a IPADDRS" to receive the netbios stats of this. a program that can handle this automaticaly is not well known.

Hi,
  This tool is also not working.
  I get the below result, and you can see it is not working.
Thanks!!
