Assume the linksys and cisco servers are both assigned static IP addresses (192.168.0.1 & 192.168.0.249). Furthermore, assume the DHCP server has been granted the largest, contiguous block of available IP addresses in the subnet range to give out as dynamic IP addresses.

Question 10 (1 point)

Assume the linksys and cisco servers are both assigned static IP addresses (192.168.0.1 & 192.168.0.249). Furthermore, assume the DHCP server has been granted the largest, contiguous block of available IP addresses in the subnet range to give out as dynamic IP addresses.

Mathematically speaking, what is the first possible IP address in the DHCP server's pool for addresses?

Answer 1

To answer the questions, we need to assume some details about the subnet structure based on the given IP addresses.

1. Calculate the DHCP Pool Size:

   • The static IP addresses assigned are 192.168.0.1 (Linksys server) and 192.168.0.249 (Cisco server).
   • Generally, a typical subnet for private IP addressing in the 192.168.x.x range is /24 (which corresponds to a subnet mask of 255.255.255.0).
   • In this case, a /24 subnet contains IP addresses from 192.168.0.0 to 192.168.0.255. This amounts to a total of 256 IP addresses.
   • Since both 192.168.0.1 and 192.168.0.249 are assigned as static IPs, those two addresses cannot be assigned out by the DHCP server.

   Therefore:

   • Total addresses available in the /24 subnet = 256
   • Static addresses used = 2 (192.168.0.1 and 192.168.0.249)
   • Hence, the number of IP addresses available in the DHCP pool = 256 - 2 = 254 IP addresses.

2. Total Client Addresses:

   • In a /24 subnet, the number of total addresses available (including the network and broadcast addresses) is calculated as:
   • Network address: 192.168.0.0 (not usable for hosts)
   • Broadcast address: 192.168.0.255 (not usable for hosts)
   • Therefore, total usable addresses for clients is 256 (total) - 2 (network and broadcast) = 254 client addresses.

3. First Possible IP Address in the DHCP Server's Pool:

   • Since 192.168.0.1 is statically assigned, the DHCP pool for dynamic IP assignments starts after that. The next available IP address after 192.168.0.1 would be 192.168.0.2.

To summarize:

• Question 8: 254 IP addresses in the DHCP pool
• Question 9: 254 total client addresses
• Question 10: 192.168.0.2 as the first possible DHCP address
