dhcp address - Tilted Forum Project Discussion Community

Does anyone know how to find your dhcp address(not local)?

Konichiwaneko · 07-07-2003, 09:59 PM

dhcp is automatically assigned. Are you looking for your dhcp server address, or your address that was assigned to you?

Do you mean IP address also?

ZeroDoom · 07-07-2003, 11:04 PM

Im looking for the dhcp server address.

charliex · 07-07-2003, 11:14 PM

if its windows you are asking about ipconfig /all will show it

ZeroDoom · 07-07-2003, 11:49 PM

That just shows me the Local dhcp server address.

charliex · 07-08-2003, 12:02 AM

i'm confused as to what you are looking for ? The local DHCP server is the one handing out addresses ?

Are you talking about a DHCP setup with a root DHCP then subsequent DHCP servers running from that ? To find the address of that, you'd query the DHCP server of the child.

What you trying to achieve ?

Konichiwaneko · 07-08-2003, 05:40 AM

go to command prompt and run a tracert on a like yahoo.

It probably is one of those.

That should print out the IP address your router got. This is, assuming, you are behind a router, and the DHCP address you got from ipconfig /all was the DHCP address granted to your computer by your router.

i agree with the last one, i use it all the time for my customers (internet tech support). it's quicker than me looking it up in our tools

It's only going to be one of these if you are behind a router and the router is acting as the DHCP server. Otherwise it probably won't be one of those.

The original question is rather confusing. Further clarification would be greatly appreciated.

I'd like to add that your Server will be listed as Default Gateway or something with Gateway in it.

and if thats not what you ment... more info would be appreciated =P

tinfoil · 07-09-2003, 12:25 PM

Not to get nitpicky, but as hrdwareguy says, the default gateway will not always be the DHCP server. At the office here I set the DHCP server to .3 and the gateway to .1 as they are both physically different machines. Therefore, the DHCP server will not show up on the traceroute.

maybe this we are helping him with a dos attack

?

This may work depending on your situation. Asssuming a modern MS Windows System:

If you are not communicating with other machines locally, try running an arp -a after booting up.

Or you could do this in a batch file during operation:

arp -d *
ipconfig /release
ipconfig /renew
arp -a

If you only have one entry after running this, the entry is your DHCP server.

acostello · 07-11-2003, 01:58 PM

DHCP Servers respond to client query. One may have DHCP server anywhere on the 'net - The router (next hop) of your ISP/Provider will forward queries to the appropriate DHCP server - That server will dish out a lease. I have seen multiple DHCP servers, serving out IPs -

What is it that you are trying to solve ? or acomplish ? That will help folks help you

Peetster · 07-11-2003, 03:42 PM

ZeroDoom, why not tell us what you are trying to do? There is a chance that you don't need your DHCP server's IP address at all. Personally I can't think of a single use for that info. The DHCP server hands out IP addresses even before your OS is loaded. What's your situation?

Pragma · 07-22-2003, 05:24 PM

Your local DHCP server will show up with an ipconfig /all in Windows. As for that only showing the "local" DHCP server, I think I might know what you mean.

If your network setup is Internet <-> Cable Modem/Router <-> Internal Network, then your machine will only show the Cable Modem as the DHCP server. If you want to find your ISP's DHCP server, that's another matter. Let me know if I'm on the right track.
