A network architect is establishing standard address allocations and boundary checks for an enterprise network redesign. Match each IPv4 address block or prefix range on the left with its corresponding RFC 1918 classification, CIDR specifications, or Internet routing characteristics on the right.
- A single Class A private block providing total addresses across the range to
- A set of contiguous Class B private subnets spanning to
- A set of contiguous Class C private subnets spanning to
- Globally routable public IPv4 address space spanning to located outside RFC 1918 boundaries
Cevap
10.0.0.0/8 matches the single Class A private block (10.0.0.0 to 10.255.255.255); 172.16.0.0/12 matches the 16 contiguous Class B private subnets (172.16.0.0 to 172.31.255.255); 192.168.0.0/16 matches the 256 contiguous Class C private subnets (192.168.0.0 to 192.168.255.255); 172.32.0.0/11 matches the globally routable public address space.
Each item matches its corresponding RFC 1918 definition or boundary specification correctly: 10.0.0.0/8 is the single Class A private block, 172.16.0.0/12 spans 16 contiguous Class B private /16 networks (172.16.0.0 - 172.31.255.255), 192.168.0.0/16 spans 256 Class C /24 networks (192.168.0.0 - 192.168.255.255), and 172.32.0.0/11 consists of public addresses immediately above the 172.31.255.255 RFC 1918 upper bound.
