A numerical sequence adopted by a ahead slash and a quantity represents an Web Protocol Model 4 (IPv4) deal with coupled with a Classless Inter-Area Routing (CIDR) block. The deal with itself, on this occasion, designates a selected location inside a community.

For instance, the “/29” signifies that the primary 29 bits of the deal with are devoted to figuring out the community, whereas the remaining bits establish the host inside that community.
This notation is essential for environment friendly IP deal with allocation and routing. It permits community directors to subdivide networks into smaller, extra manageable subnetworks, optimizing using out there IP deal with area. Traditionally, this methodology changed classful networking, which was much less versatile and led to IP deal with exhaustion. The usage of this notation permits extra granular management over community segmentation and safety insurance policies.
