Correct Answer:
A. DHCP server
Explanation:
A DHCP server is the network device responsible for dynamically assigning IP addresses to hosts within a local area network. It automates the distribution of critical network parameters—including IP addresses, subnet masks, default gateways, and DNS server addresses—from a centralized pool or scope. This process, often following the DORA (Discover, Offer, Request, Acknowledge) sequence, ensures efficient address management, prevents manual configuration errors like IP conflicts, and allows for the recycling of addresses through a lease system. Although routers, switches, or dedicated servers can perform this function, the specific role of managing and allocating these dynamic configurations belongs to the DHCP service.
