Why medium size or large size corporation does not want a block of class c address?

Medium to large corporations typically avoid Class C IP address blocks due to their limited number of usable IP addresses, usually ranging from 1 to 254. This restriction can hinder scalability and growth, as businesses often require more IP addresses for expanding networks, devices, and services. Additionally, Class C addresses can lead to inefficient network management and segmentation challenges, making larger Class A or B blocks more appealing for their flexibility and capacity.
