To determine the last possible IP address in the DHCP server's pool, we need to clarify the static IP addresses and identify the range of available addresses in the subnet.
Given:
- Static IPs:
- Linksys server:
192.168.0.1 - Cisco server:
192.168.0.249
- Linksys server:
These static addresses indicate that they are used and cannot be assigned by the DHCP server.
Subnet Information:
Assuming that both static IP addresses are in the same subnet, we also need to define the subnet mask. The typical subnet mask for the private class C network (which 192.168.x.x falls into) is 255.255.255.0. This gives a subnet range of:
- Network Address:
192.168.0.0 - Usable IP Address Range:
192.168.0.1to192.168.0.254 - Broadcast Address:
192.168.0.255
Availability of IP Addresses for DHCP
-
Static IPs Occupied:
- Linksys:
192.168.0.1(1st usable IP) - Cisco:
192.168.0.249
- Linksys:
-
Remaining Usable IP Range: From the usable IP range
192.168.0.1to192.168.0.254, we remove the two static IPs.
- Usable IPs:
192.168.0.2to192.168.0.248(This actually consists of the usable IP range minus the two static IPs)
Last Possible IP Address in the DHCP Pool
Since 192.168.0.249 and 192.168.0.1 are occupied, the last available IP address in the DHCP pool would be:
- Last DHCP Address:
192.168.0.248
CIDR Notation for the Subnet
Given that the subnet mask for the private network is 255.255.255.0, we can calculate the CIDR notation:
- The subnet mask
255.255.255.0corresponds to/24(because 255 has eight 1's in binary, and there are three 255s and one additional zero, hence 24 bits).
Summary
- Last Possible IP Address in DHCP Pool:
192.168.0.248 - CIDR Notation for the Subnet:
/24
This all provides clarity on the last available IP address and the appropriate CIDR notation for the subnet.
