It's a shorthand way of writing an IP address range, where instead of using _first address-last address_, you denote the first IP address in a given range and then the number of 1 bits from the left to the right that represent the subnet mask. The 1-bits in that mask mark the bits that stay the same across all addresses in a specified range written in binary. Let's take my homelab VLAN's range for example: `10.0.10.1/24`. The first address in the range is `10.0.10.1`, and the first 24 bits in the address stay the same. Since each one of four numbers cannot be greater than 255, it means that each part fits perfectly in 8 bits.
