📢📢 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!

[Ed Harmoush @ed_pracnet]

- 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"

[Ed Harmoush @ed_pracnet]

PS: I'm also shortly releasing a new version of Subnet IPv4 .com

If you want to beta test it, reply with ➕ plus emoji and I'll DM you the link.
