Find the IP address of your DHCP server.

Question

Find the IP address of your DHCP server.

Ok so Im not sure if this will help many of you but since it took 3 of us to figure this out and since the place I found the answer was not Apple, i figured it was worth a post here.

to find the IP address of your DHCP server type the following command into terminal:

ipconfig getpacket en1 (or en0)

look for server_indentifier (ip) = your DHCP server's IP address

this command will also give you a ton of other info such as:

yiaddr = Your IP address

siaddr = Server Address

giaddr = gateway IP address

chaddr = Hardware Address

Other options would be:

system_profiler SPNetworkDataType | grep "Server Identifier"

and to narrow down the one you used:

ipconfig getpacket en0 | grep siaddr

ipconfig getpacket en1 | grep siaddr

There may be some mileage in using ifconfig as well? If you're connected over Wi-Fi holding down the option key whilst clicking on the Airport Icon in the Menu Bar will also show you the WAP's IP address, which in some cases will also be the DHCP server.
