Because a DHCP server can interact with a BOOTP client, you can use the DHCP server to configure
an IP address for the BOOTP client, without any BOOTP server.

Obtaining an IP Address Dynamically

A DHCP server can take the place of the BOOTP server in the following dynamic IP address
acquisition.

A BOOTP client dynamically obtains an IP address from a BOOTP server in the following way:

1) The BOOTP client broadcasts a BOOTP request, which contains its own MAC address.

2) The BOOTP server receives the request and searches the configuration file for the corresponding

IP address according to the MAC address of the BOOTP client. The BOOTP server then returns a
BOOTP response to the BOOTP client.

3) The BOOTP client obtains the IP address from the received the response.

Protocols and Standards

Some protocols and standards related to BOOTP include:

z

RFC 951: Bootstrap Protocol (BOOTP)

z

RFC 2132: DHCP Options and BOOTP Vendor Extensions
