Yes, DHCP (Dynamic Host Configuration Protocol) primarily uses UDP (User Datagram Protocol) for its communication. Specifically, it operates over UDP ports 67 and 68, where the server listens on port 67 and clients use port 68 to send requests. This choice of UDP allows for a lightweight, connectionless protocol suitable for the dynamic nature of IP address assignment in networks.
UDP and ports 67 and 68.

The port that automates the assignment of IP addresses on a network is typically associated with the Dynamic Host Configuration Protocol (DHCP). DHCP servers use UDP (User Datagram Protocol) on port 67 for incoming requests from clients and port 68 for client responses. This protocol allows devices on a network to automatically receive IP addresses and other configuration settings, simplifying network management.
DHCP, or Dynamic Host Configuration Protocol, is a language computers use to ask for an IP address when first connecting to a network. It is used to assign IP addresses and network information so the new computer can connect to various other servers running on the network. A residential router or gateway automatically performs these functions. It is importand that each network only include one DHCP server, or conflicts could occur. Depending on circumstances and the way the server was setup, it may accept or deny the request. The latter case being the computer will not be able to communicate on the network.

DHCP is good if you've got a network that changes constantly. If you owned a hotel that offered free in-room high-speed Internet over Ethernet, DHCP would make your life much simpler: instead of issuing a static IP address to every guest, you'd just tell them to set their laptops to use DHCP and plug into the jack in the wall. If you're running a network that doesn't change much over time, you can still use DHCP but I think it's kinda silly--it's as easy to plug in an IP address and subnet mask as it is to use DHCP.
By default, these are ports 1717 and 2504 UDP.
The four primary functions of DHCP (Dynamic Host Configuration Protocol) are: IP Address Allocation: DHCP automatically assigns IP addresses to devices on a network, ensuring that each device has a unique address. Configuration Information: It provides essential network configuration parameters, such as subnet mask, default gateway, and DNS server addresses. Lease Management: DHCP manages the lease of IP addresses, allowing addresses to be reused and ensuring efficient use of the available IP address space. Dynamic Updates: It enables devices to request new IP addresses as needed, facilitating easy network changes and mobility for devices.
According to Microsoft:How to use automatic TCP/IP addressing without a DHCP server"A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance."For more information, see Related Links, below.
