    IP Tracing

    Is there a utility or MSDos command I can run to trace an IP address and retrieve the computer name that has that IP address. Thanks for any help.

    Re: IP Tracing

    You are talking about "reverse DNS". There are many sites that offer you a "lookup" search function, for example:

    http://cc-www.uia.ac.be/ds/nslookup.html

    There are also sites that offer "whois" functions, for example:

    WhoIs

    But if you want something that is a simple DOS utility to do reverse DNS, you have a couple of choices -- depending on your OS. For WinNT/2K/XP, I think you *might* be able to simply use "nslookup" at the DOS prompt. I am really not sure if it is installed with EVERY version of WinNT-XP, but here is the MS word on that utility:

    Using NSlookup.exe

    There are also third-party nslookup utilities that can work on every Windows version:

    NSLOOKUP for WINDOWS

    I happen to use "nslook" from PC Pitstop:

    Under NT you probably have tracert (trace route). Tracert accepts either the IP or name of the machine you want to reach, and shows the machine name (or IP) of the machine if available.

    TRACERT should exist under all versions of Windows. In 2000 and later there is also PINGPATH - an interesting utility.

    Trent--
    AnalogX has a GUI version of Traceroute, called HyperTrace that shows you the hops, machine names, routes quickly. And a good price--it's free as are the other 80 plus interesting downloads in four main categories. Always a site worth checking out.

    Re: IP Tracing

    Thanks for the replies. I should have explained it better, this is for LAN. There is a computer or printer that has a IP address and I need it to be released, because I want to statically assign it, it has been handed out from DHCP. I'm trying some of the things that everyone has posted. I hope one of them work. Thanks again

    Re: IP Tracing

    If you're trying to release a DHCP lease, all you need to do is to run WINIPCFG and click on the Release All button (in Windows 95, 98 and ME) or IPCONFIG /RELEASE (in Windows NT/2000/XP) from a command prompt.

    Anything more than that, such as forcing the DHCP server to assign you a static address, would need to be done at the console of the DHCP server. For your reference, typicallty addresses in the x.x.x.100 to x.x.x.250 range are reserved for DHCP clients, although a system administrator could easily change that, or force the DHCP server to reserve an address for a particular machine.

    HTH,

    Re: IP Tracing

    Mark - I couldn't find pingpath on W2K or XP Pro. Is it not in the path by default, or maybe part of a resource kit? Thanks!

    <img src=/S/doh.gif border=0 alt=doh width=15 height=15> I had a case of the "shoulda gone to bed earlier blues" - I reversed that. The actual EXE is pingpath. Try that instead. <img src=/S/blush.gif border=0 alt=blush width=15 height=15>

    Re: IP Tracing

    OK, I'm really out of it today. I'm glad you figured out what the heck I was trying to say, because I surely can't get it right. Off to my extended nap! <img src=/S/flee.gif border=0 alt=flee width=25 height=25> <img src=/S/headthrob.gif border=0 alt=headthrob width=15 height=15> <img src=/S/doze.gif border=0 alt=doze width=15 height=15> <img src=/S/snore.gif border=0 alt=snore width=32 height=15>
