📢📢 Introducing the new version of SubnetIPv4․com
Over the last few months I've worked with a developer to make one of the best tools to practice Subnetting in IPv4 even better!
- Auto Fill Non-Interesting Octets -- so you don't have to bother with re-typing octets that are largely arbitrary to actual Subnetting
- Auto Check -- so you can test yourself and see whether your answers are correct "in real time"
This was initially a teaching tool for my students, but I thought to give it to the world in hopes that other students (or teachers!) can use it to help in the learning journey.
