DHCP vs. BOOTP: Know the Difference
By Shumaila Saeed || Published on February 20, 2024
DHCP is a dynamic network management protocol offering flexible IP address assignment; BOOTP, its predecessor, is a simpler, rigid protocol primarily for booting diskless workstations.
Key Differences
DHCP, or Dynamic Host Configuration Protocol, dynamically assigns IP addresses to devices on a network, allowing for efficient management and reuse of addresses. It supports automatic, dynamic, and manual allocation of IP addresses. In contrast, BOOTP, or Bootstrap Protocol, was designed for manual allocation of IP addresses and is used for booting diskless workstations connected to the network.

A major feature of DHCP is its ability to lease IP addresses for a set period of time, automatically reassigning the address when the lease expires. This approach ensures optimal use of limited IP address resources. On the other hand, BOOTP assigns IP addresses with an expectation of permanence, which can lead to inefficient usage of IP addresses in environments with frequently changing devices.

DHCP supports a broad range of configuration options, including subnet masks, default gateways, and DNS server addresses, making it highly versatile for various network configurations. Conversely, BOOTP, while it also supports automatic IP address assignment and additional network information, is more limited in scope and lacks some of the advanced features and flexibility of DHCP.

DHCP is designed to work well in networks where devices frequently join and leave, such as Wi-Fi networks, making it ideal for modern, dynamic network environments. BOOTP, initially developed for initializing diskless workstations, is less suited for dynamic network environments and is better for static network configurations.

The protocol complexity of DHCP is higher than that of BOOTP, reflecting its more advanced capabilities. DHCP's complexity is justified by its greater flexibility and ability to handle a wide range of network configurations. BOOTP is simpler, but its rigidity and lack of features compared to DHCP make it less suitable for modern, frequently changing networks.

DHCP and BOOTP Definitions
DHCP
DHCP supports both dynamic and static IP address allocation, catering to different network needs.
In our network, DHCP assigns fixed IP addresses to servers and dynamic addresses to client devices.

BOOTP
BOOTP is used for manual allocation of IP addresses and bootstrapping diskless workstations.
We used BOOTP to configure IP addresses for our diskless network terminals.

DHCP
It allows for automatic configuration of network parameters such as subnet masks and gateways.
With DHCP, our devices automatically receive the correct subnet mask settings.

BOOTP
It provides network information to devices but lacks dynamic address allocation capability.
BOOTP assigned a permanent IP address to our legacy server.

Jan 17, 2024
DHCP
DHCP is capable of temporarily leasing IP addresses and reallocating them as needed.
The DHCP server leases IP addresses for 24 hours before reassigning them.

BOOTP
BOOTP does not support the temporary leasing of IP addresses like DHCP.
Unlike DHCP, BOOTP's IP address assignment for our devices is permanent.

DHCP
DHCP dynamically assigns IP addresses to devices on a network to efficiently manage address space.
Our office network uses DHCP to automatically assign IP addresses to employees' laptops.

BOOTP
BOOTP is simpler and more rigid compared to DHCP, with fewer configuration options.
Our older network setup relies on the simplicity of BOOTP for device configuration.

DHCP
It reduces the need for manual network configuration, simplifying network management.
Thanks to DHCP, we no longer manually configure IP settings for each device.

BOOTP
Originally designed for bootstrapping computers without their own storage, BOOTP is now less common.
In the past, BOOTP was essential for initializing our diskless clients.
