It is CIDR. Just putting this to get the community vote for CIDR.

A. CIDR (Classless Inter-Domain Routing)

A. CIDR (Classless Inter-Domain Routing) A /28 notation is a part of CIDR (Classless Inter-Domain Routing), which is a method for allocating IP addresses and routing Internet Protocol packets efficiently. In CIDR notation, the /28 indicates the prefix length or subnet mask, specifically that the first 28 bits of the address represent the network, and the remaining bits represent host addresses. CIDR notation is used to specify network addresses and subnet masks in a more flexible and efficient way than the traditional classful addressing system. This notation allows for more precise allocation of IP addresses and is a key component of modern IP address management.

Of course CIDR

A: Classless Inter-Domain Routing (CIDR) is a group of IP addresses that are allocated to the customer when they demand a fixed number of IP addresses. In CIDR there is no wastage of IP addresses as compared to classful addressing because only the numbers of IP addresses that are demanded by the customer are allocated to the customer. The group of IP addresses is called Block in Classless Inter - Domain (CIDR). CIDR follows CIDR notation or Slash notation. The representation of CIDR notation is x.y.z.w /n the x.y.z.w is IP address and n is called mask or number of bits that are used in network id. https://www.tutorialspoint.com/what-is-cidr-and-how-it-works
