A systems administrator notices that 2 machine on a newly provisioned VLAN is having trouble connecting to the internet. The IP address is 192.168.10.10 with a subnet mask of 255.255.254.0. The…

Changing the machine IP to 192.168.10.131 would place it in the second half of the /25 subnet, which still wouldn't resolve the fundamental subnet mask mismatch for the gateway.

Changing the default gateway to 192.168.0.254 would place the gateway outside the machine's 192.168.10.0 network entirely, preventing connectivity.

Adding a static route is for routing traffic to remote networks; the issue is local subnet communication, as the gateway is reportedly reachable.

The machine is configured with IP 192.168.10.10 and subnet mask 255.255.254.0 (a /23 network), while the network team states the subnet is 192.168.10.0/25 (192.168.10.0-192.168.10.127). Changing the subnet mask to 255.255.255.128 (a /25 mask) will ensure the machine's IP and the gateway (presumably within the 192.168.10.0/25 range) are on the same local subnet, allowing direct communication.
