A network engineer is troubleshooting connectivity for a newly installed server on an existing VLAN.

The server’s subnet mask is 255.255.255.224 (/27), which covers IPs from 192.168.100.224 to 192.168.100.255. However, the router only recognizes 192.168.100.0/24, indicating a mismatch between the server’s subnet and the router's network.

Correct mask for the /24 network is 255.255.255.0, allowing 256 IPs from 192.168.100.0 to 192.168.100.255.

This mismatch would result in routing issues, especially with the gateway outside of the subnet range.
