"Explain the concept of CIDR (Classless Inter-Domain Routing) and its role in modern IP networking. Discuss how CIDR enables more flexible allocation of IP addresses by allowing variable-length subnet masking. Describe the structure of CIDR notation and how it represents both IP address and subnet mask information. Explore the benefits of CIDR, such as efficient address allocation, route aggregation, and improved scalability in the context of internet routing. Additionally, discuss the relationship between CIDR and IPv6 adoption."
