the subnet net zero is not according to cisco. It is according to the router.

When a router has

ip subnet-zero

enabled. Then the subnet 0 is the first subnet.

Technically he is right, BUT more often than not you will see subnet zero being used, and has been used for some time now.

Yup, by default it is enabled on most cisco routers/L3 switches shipped today.

Haha yeh, please dont search for threads regarding ip subnet zero off or on for the exams, it will probably crash the server and Johan will be maaaaaaaaadddd. BUT seriously, cisco will always say on or off for subnetting questions and for sims you can see the running config, so nps there.
