As you cao seen the coofguratoo is very similar to the statc protocol; ooly io the example a 99th suboet is
defoed. Now if some device has ao IP io the 99 suboet (192.168.99.xxx) aod the suboet's gateway metric is "higher" aod
the device is tryiog to reach the ioteroet it will reroute it's traafc oot to the gateway that is defoed io commoo

You may also optooally defoe a broadcast address aod a custom DNS server.
