Tentang CIDR Trainer
CIDR Trainer trains users to perform network subnet calculations. It uses directed training drills while providing documentation to instruct users to perform each step of network subnetting calculations.
CIDR Trainer includes IPv4 and IPv6 CIDR calculators.
Version 1.1 includes the following categories of drills:
1-digit hexadecimal and binary drills
2-digit hexadecimal and binary drills
IPv4 terminology drills
IPv4 prefix-length drills
IPv4 CIDR drills
IPv6 Address Shortening and Lengthening Drills
IPv6 Terminology Drills
IPv6 CIDR Drills
IPv4 and IPv6 CIDR Calculators
You may try each training drill for free 20 times. After that you may try the other drills or purchase a permanent unlock of all training drills for a low price (see in-app purchases for the "forever full-unlock" price in your region). One purchase unlocks all versions of the app (iOS, iPadOS, and MacOS). CIDR Trainer uses iCloud to sync drill progress between your devices.
Each training drill has a "help" button in the top-right which provides related documentation
