I keep seeing sometimes the question being marked as 'off topic' and don't get a clear reason why it is marked so. I would like to understand what is the scope of Network Engineering community. Where is it explained? So that it helps the community as well from getting unrelated posts
First item on the help center: https://networkengineering.stackexchange.com/help/on-topic
No question is ever closed on a SE site without a reason given. While there may or may not be a comment by those closing the question, the close statement always provides some sort guidance to what is wrong and at least one link to the help center.
For example, a question closed for being off topic includes this text on our site:
This question appears to be off-topic. The users who voted to close gave this specific reason:
"NE is a site for to ask and provide answers about professionally managed networks in a business environment. Your question falls outside the areas our community decided are on topic. Please visit the help center for more details. If you disagree with this closure, please ask on Network Engineering Meta." – (name)
If this question can be reworded to fit the rules in the help center, please edit the question.
Following the first help center link takes you directly to the ‘What topics can I ask about here?’ page. The second goes to the ‘What does it mean if a question is "closed" or "on hold"?‘
There is specific text associated with each close reason with typical examples being provided by the second link.
