The CIDR Deployment Working Group will be a forum for coordinating the deployment, engineering, and operation of classless routing protocols and procedures in the global Internet. This activity will include, but not be limited to: - Deployment of CIDR addressing and routing in the global Internet. Will include coordination of deployment of new exterior routing protocols, such as BGP4, which support CIDR. - Develop mechanisms and procedures for sharing operational information to aim the operation. - Development of procedures, policies, and mechanisms to improve the utilization efficiency of the IPv4 address space. - Work on longer-term strategies for hierarchical, CIDR-based addressing and routing. Examples include class A subnetting and provider block sub-allocation along geographical/topological boundaries as is done for 193.0.0.0 and 194.0.0.0 in Europe. Initially, this working group will be simply the reincarnation of the BGP Deployment Working Group under a new name.
