Question from a member about IPv4 (subnets) terminology
A big thank you to for his question about IPv4 terminology. He sent the question as a private chat, but I want to make sure everyone got to see the reply.
My reply is a little bit long to type all here, so I wrote a tutorial and put it on my blog. You can read the entire reply here https://blog.anythingoverip.com/subnetting-vocabulary-decoded-understanding-the-language-of-ip-addressing/
Once you have read the post, jump back here to answer this question.
## Practice Challenge
Given: `10.20.30.40/28`
- What's the subnet mask in dotted decimal?
- What's the network address?
- What's the broadcast address?
- How many usable host addresses?
- Is `10.20.30.60` in the same subnet?
Post your answers in the comments - no judgment, we're all learning!
P.S - here is a playlist of some videos I made on YouTube MANY MANY years ago, but they are still 100% accurate with IPv4 address - https://www.youtube.com/playlist?list=PLx49hr6omlDuDCBxwMS-wA3AQM7tHUcPa
