I have added a page to the site that should help folks practice their subnetting skills. Check it out here practicesubnetting.php. Let me know if you see any issues or have a suggestion.

If you bloggers would mention it in your blog and maybe provide a perma-link, that would be appreciated.

Nice work!

Thank you.

suggestion, use cider in the question, /i.e 192.168.1.23/28
provide the subnet in the answer i.e. 255.255.255.240

makes it a bit more complicated, but drives home the CIDR to subnet mask translation
which is an important thing to remember.

Looks great! Good call.

Yeah, my only thought would be (like ristau) to add the CIDR form. It would probably help newcomers make a 1-to-1 correlation between 255.255.255.252 and /30, for example.

Ok, Aubrey suggested that as well. I will get that implemented.

I linked earlier, forgot to post.

Linked as well.

CIDR bits added and new step created in the 'Reveal The Work' section to help convert it. Anything else?

think you have just made me understand subnetting for the first time in 3 years
