Your ISP has one DHCP server somewhere on their network and you have one DHCP server somewhere on your network.
On a home network the DHCP service is normally run on the router.
On a business network the DHCP service will be on one of their servers, probably whatever is running DNS.
How do I find my DHCP?
You can get the IP address of the server by running ipconfig /all on a windows machine, and then you can get the MAC address by looking for that IP address using arp -a .
