What is the DHCP term for the range of IP addresses that a server may lease to clients?

• A. Pool
• B. Range
• C. Block
• D. Scope

Answer: (D)

In DHCP, a scope defines the set of IP addresses the server can hand out to clients within a subnet, along with the associated options like the subnet mask, gateway, and DNS servers. It’s the managed range from which addresses can be leased, plus any exclusions or reservations and the lease duration. When a client requests an IP, the server selects one from this scope and assigns it, ensuring addresses aren’t reused in conflicting ways. That’s why this term is the best fit: it captures not just a fixed list of addresses, but the configured range plus the policies and options that govern how those addresses are issued. While people might casually refer to a pool or range, the authoritative DHCP term for this defined set of leasable addresses is scope. A block isn’t a standard DHCP term, so it doesn’t describe the concept accurately.
