WebSep 16, 2024 · The VPC route table uses the Prefix List as the destination with the transit gateway as the next hop. This greatly simplifies the VPC route table, and makes administering the network CIDR ranges of the Edge VPC (the one the traffic is meant for) easier by consolidating destination CIDR ranges in the Prefix List.

WebThe calculation is quite simple. To calculate the number of available hosts in a subnet, raise 2 to the power of 32 minus the number of subnet bits and subtract 2. The formula is (2 ^ (32 - n)) - 2, where n is the number of bits in the subnet mask. For example, a /24 subnet has (2 ^ (32 - 24)) - 2 = 254 assignable hosts. WebSubnet Prefix CIDR notation.
