Yes, MikroTik, like many other network-based systems, uses network prefixes (known as Classless Inter-Domain Routing (CIDR) notation) in addition to traditional netmasks.

CIDR prefix notation is a more compact and flexible way to specify blocks of IP addresses and their corresponding masks.

For example, instead of typing an IP address and its netmask as 192.168.1.0 with mask 255.255.255.0, in CIDR notation it would simply be written as 192.168.1.0/24.

The number after the slash (/24) indicates how many consecutive bits in the mask are '1', which simplifies both network configuration and calculation in routing and subnet management.

MikroTik RouterOS allows you to use both formats in your network configuration, but the CIDR notation is generally more common in modern networking documentation and practices due to its simplicity and efficiency in handling various subnet sizes.
