AWS announces Amazon provided contiguous IPv6 CIDRs blocks
AWS announces the general availability of Amazon provided IPv6 contiguous Classless Inter-Domain Routing (CIDR) blocks with Amazon VPC IP Address Manager (IPAM). Within IPAM, customers can create IPv6 publicly scoped pools and provision with BYOIP CIDR blocks. Now, customers can provision Amazon provided IPv6 CIDR blocks from /52 up to /40 in size into separate pools for association to Virtual Private Clouds (VPCs). Contiguous CIDR blocks can be used for sequential VPC creation. CIDRs can then be aggregated in a single entry across networking and security constructs like access control lists, route tables, security groups, and firewalls.
