1. DHCP was designed to replace the older BOOTP
2. BOOTP can only provide an IP to a computer while it is booting while DHCP can provide an IP when the OS is already loaded
3. DHCP is primarily used to seamlessly provide IP addresses to computers while BOOTP is used to configure and boot diskless computers or thin clients
4. BOOTP has a 30 day lease on the IP address as a default while DHCP only sets 8 as a default
5. DHCP can automatically rebind or renew their leases while BOOTP requires a system restart

∙ 12y agodhcp and bootp both runs over UDP. DHCP is based on bootp with some backward compatibility. BOOTP was designed for pre configuration of host information in a databse server.................................while DHCP allows for dynamic addressing ( network addresses) configuration for newly attached hosts.
with addition DHCP allows for recovery and reallocating network addresses through leasing mechanism...
I hope you found an answer of the precursor BOOTP and the new advanced DHCP.

∙ 9y agoRARP and BOOTP protocol do not gives the four characteristics required. DHCP on the other hand is dynamic and gives all the four address.

How does DHCP allow devices to communicate?
They use DHCP to assign IP Addresses to Devices such as Windows XP, Networking flashcards, OIt DHCP and BootP services, and connecting routers. The definition for DHCP is Dynamic Host Configuration Protocol.
What is the bootp protocol used for?
BOOTP (Boot Protocol) may be used to boot remote computers over a network. All major Operating Systems, such as Mac OS X, IBM AIX, Solaris and HP, (excepting Windows) support BOOTP. The concept allows a 'diskless' system to avoid installing (and maintaining) the software on every desktop. The downside is network workload takes a big hit, even to paging over the network. This then requires more BOOTP servers and fewer systems on each subnet.
What are User Classes and Vendor Classes in DHCP?
http://support.microsoft.com/kb/266675 The following list contains pre-defined vendor classes that are available in Windows 2000 DHCP server. Collapse this tableExpand this table {| ! Class Data ! Class Name ! Description | MSFT 5.0 Microsoft Windows 2000 options Class that includes all Windows 2000 DHCP clients. MSFT 98 Microsoft Windows 98 options Class that includes all Windows 98 and Microsoft Windows Millennium Edition (Me) DHCP clients. MSFT Microsoft options Class that includes all Windows 98, Windows Me, and Windows 2000 DHCP clients. |} If you have non-Microsoft DHCP clients, you can define other vendor-specific classes on the DHCP server. When you define such classes, make sure the vendor class identifier that you define matches the identifier used by the clients.

When you configure such classes, you must specify a custom identifier that corresponds to the user class defined on the DHCP server.

What ports are used by dhcp and the DHCP client?
The port 67 and port 68 are used by DHCP and the DHCP clients.
What is the use of a DHCP relay agent?
The use of a DHCP relay agent is an agent that relays DHCP between DHCP clients and DHCP servers on different IP networks. The DHCP relay agent is compliant with RFC 1542.
DHCP is based heavily on which protocol?
BOOTP
What sophisticated IP addressing utility has surpasses BOOTP?
DHCP
How are bootp and dhcp related?
they both run on the same port number
What protocols have made rarp largely unnecessary on modern tcp ip networks?
BOOTP, and eventually DHCP, replaced RARP. Both BOOTP and DHCP offer a more robust, flexible method of assigning IP addresses.

What roles do DHCP and DNS play?
DHCP is a host configuration protocol and is dynamic . DHCP is short for Dynamic host configuration protocol and is backward compatible with earlier protocols like BOOTp . DNS is domain name system that maps name to an IP address.
Which protocol is used to set the IP address?
The older protocol for this purpose was BOOTP, but modern addressing LAN schemes today will use DHCP.
What is the main difference between bootp and dhcp?
Dhcp is Direct host configure protocol. This is used to assign IP address Automatically. In a Domain Environment we must need IP Addresses to communicate with one machine to another to access the resources, their are mainly two ways to configure a IP in a system One is static or manual IP and other is Dynamic or Automatic IP. So DHCP help us to configure an IP Address Dynamically.(Network+ Guide to Networking answer)BOOTP relies on a static table to associate IP addresses with MAC addresses, whereas DHCP does not
In most cases BOOTP has been surpassed by the more sophisticated IP addressing utility?
In many industrial applications, DHCP is not used because it is desired for devices to have the same IP address all the time, whereas in an office application it doesn't really matter if you get a different IP address from the network every time. Some industrial Ethernet devices, like I/O for EtherNet/IP, are BootP enabled in their default out-of-box settings. Thus, in the industrial world, BootP is still used and widely accepted as a quick and simple way to give devices an IP address. Phoenix Contact has a simple, freeware BootP server that can be used for this purpose which can be downloaded at the link below.
What is DHCP scope and why it is required?
DHCP Gives four piece of information that are required in a network today. The four piece of information are IP address of computer , IP address of router , Subnet mask and IP address of name server. DHCP is a dynamic host configuration protocol and is backward compatible with BootP.
What is dhcp scope and why is it required?
DHCP Gives four piece of information that are required in a network today. The four piece of information are IP address of computer , IP address of router , Subnet mask and IP address of name server. DHCP is a dynamic host configuration protocol and is backward compatible with BootP.
