Question: A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 192.168.10.0/24. There are 3 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts?
- 254
- 251
- 252
- 253
Answer: The subnet 192.168.10.0/24 has a total of 256 IP addresses available, ranging from 192.168.10.0 to 192.168.10.255.
To reserve static IP addresses for the 3 printers, we need to subtract 3 IP addresses from the pool. Let’s say we reserve the IP addresses 192.168.10.2, 192.168.10.3, and 192.168.10.4 for the printers.
So now, the IP addresses available for DHCP assignment range from 192.168.10.5 to 192.168.10.255, which is a total of 251 IP addresses.
Therefore, there are 251 IP addresses left to be assigned to other hosts.
Explanation:
First, let’s start with the basics. DHCP stands for Dynamic Host Configuration Protocol. It’s a network protocol that is used to assign IP addresses dynamically to hosts on a network. The DHCP server manages a pool of IP addresses and assigns them to hosts that request an IP address.
In this case, we have a DHCP server that is configured with the address pool 192.168.10.0/24. This means that the network has a range of IP addresses from 192.168.10.0 to 192.168.10.255. The /24 in the subnet mask indicates that the network has 24 bits for the network portion of the address and 8 bits for the host portion of the address.
Now, we need to reserve static IP addresses for 3 printers on this network. To do this, we will remove 3 IP addresses from the pool of addresses that the DHCP server can assign. We will choose to reserve the IP addresses 192.168.10.2, 192.168.10.3, and 192.168.10.4 for the printers.
This means that the DHCP server can now assign IP addresses from 192.168.10.5 to 192.168.10.255. The total number of IP addresses available for DHCP assignment is 251 (since we reserved 3 addresses for the printers).
So, in summary, we subtracted 3 IP addresses from the original pool of 256 addresses (192.168.10.0/24), which left us with 251 IP addresses that can be assigned by the DHCP server.
