Dynamic Host Configuration Protocol Configuration
The Dynamic Host Configuration Protocol (DHCP) is a protocol designed to make IP
address assignment dynamic and automatic. When a router is configured in DHCP mode,
it generates a request for an IP address. The address is provided to the router and can be
used from that point forward.
In the dynamic address assignment mode, an IP address is leased to a DHCP-configured
router. You should ask your system administrator to configure your network so the router
can use DHCP and host name you have assigned to the router.
In the event you configure your router to DHCP and do not know which IP address was
assigned automatically, you can use ARP to discover which IP address was assigned to the
router by the DHCP server.
To discover which IP address was assigned to the router:
1
Follow the steps in the previous section for ARP to bind the router MAC address to a
temporary static IP address.
2
Use the command arp –g to display your computer’s the IP-to-MAC address table.
This table contains two entries corresponding to the router MAC address. One of the
entries contains the temporary static IP address you just bound to the router MAC
address, and the other entry is the DHCP-assigned IP address. You can use the DHCP
assigned address to access the router from any computer on the network.
