A DHCP server is configured with the address pool 192.168.10.0/24. If there are 3 printers that need reserved static IP addresses, how many IP addresses are left for other hosts?

A DHCP server is configured with the address pool 192.168.10.0/24. If there are 3 printers that need reserved static IP addresses, how many IP addresses are left for other hosts?

• A. 250
• B. 251
• C. 252
• D. 253

Answer: (B)

To determine how many IP addresses are available for hosts after reserving static IP addresses for the printers, you first need to understand the total number of IP addresses within the given subnet. The subnet 192.168.10.0/24 indicates a total of 256 IP addresses (from 192.168.10.0 to 192.168.10.255). However, in a typical configuration, two addresses are reserved: one for the network (192.168.10.0) and one for the broadcast address (192.168.10.255). Therefore, the usable IP addresses for assignment are reduced to: 256 total IPs - 2 reserved IPs = 254 usable IP addresses. If there are 3 printers requiring reserved static IP addresses from this pool, these reserved addresses must be subtracted from the total usable addresses: 254 usable IP addresses - 3 reserved for printers = 251 available IP addresses for other hosts. Thus, the correct answer is that there are 251 IP addresses left for other hosts after accounting for the reserved addresses for the printers.
