    * Uses the [Classless Inter-Domain Routing (CIDR) format](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) and a Class B address space.
 
-   * Uses at least a `/27` in the address space because each subnet requires 32 addresses at *minimum*. For example:
-
-     * `10.0.0.0/28` has only 16 addresses and is too small because 2<sup>(32-28)</sup> is 2<sup>4</sup> or 16.
-
-     * `10.0.0.0/27` has 32 addresses because 2<sup>(32-27)</sup> is 2<sup>5</sup> or 32.
-
-     * `10.0.0.0/24` has 256 addresses because 2<sup>(32-24)</sup> is 2<sup>8</sup> or 256. However, more addresses don't provide any additional benefits.
