[AfriNIC-rpd] Draft Policy: Anycast Assignments in the AfriNIC region

[Owen DeLong]

Walu,

Perhaps the provider in question only has a small handful (10 or so) services that they want to put up on anycast. In such a case, the /24 is usable, but, not fully utilized and the /22 would be simply a waste.

Having a dozen or so anycast services that each need an address doesn't mean you don't have other things that require unicast addresses. The current policy makes it difficult to deploy both.

But then why cant the service provider not utilize the full /22 block for anycast services?  Am thinking /22 gives you 2^10 (1,024 hosts) while /24 gives u 2^8 (256 hosts) - am not understanding what would stop the anycast service provider from making full use of the 1,024 hosts.
