您可以创建新范围（例如192.168.2.0/24），但您也需要在这些子网之间配置路由。另一种方法是将现有网络增加到/ 23（例如192.168.0.0/23）。在这种情况下，您将拥有从192.168.0.0到192.168.1.255
的地址空间，以满足您的要求。

You can create new scope (e.g. 192.168.2.0/24) but you need to configure routing between these subnets as well. Another way is to increase existing network to /23 (e.g 192.168.0.0/23). In this case you will have address space from 192.168.0.0 to 192.168.1.255 that will meet your requirements.
