I went ahead and found 10+ comments which you indicate something wasn't on topic.
Question 1: How to access LAN IP Addresses : Cisco VPN Client [on hold]
It seems you're asking about a network/vpn service that you do not
control, that makes this off-topic here (because you should simply
contact the support people for said network/vpn service.)
The question seems a little vague for it to be answered by anyone honestly. Statements like "I don't know how to connect LAN IP Addresses." don't help the reader understand the disconnect the author has. I admit this question would be on topic here, it might be closed, but its the type of question that would exist here naturally.
Question 2: Connecting/configuring two switches to a router? [closed]
host config, homework are off-topic here. this stack is for people
working in a professional environmet. this sort of Q can go on the
Super User stack.
We don't want networking engineer homework questions either. Somebody likely would have made the exact same comment, and voted the question closed, since their question is based on class material which from my perspective means the appropriate amount of research has not been done.
Question 3: What practices/ mechanisms/ protocols can be used to secure communication on physically exposed Ethernet links?
some part(s) of this might be on topic here. As it is, it's partly a
dupe (as above), partly off-topic (eg, all product recommendations are
off-topic here), so I'll close this as "too broad" ;)
If you migrated a product recomendation question to us it would be rejected by the moderators. Please don't send us this type of stuff.
Question 4: Does TCP improve the ability of IP to send really really large files? [closed]
'disgusting' seems a strange word to use; I presume this means it IS
homework, so I've closed it. None the less, welcome to our community,
where the members decided what topics/questions would be consider
on/off topic. You can refer to the Help Center and you're welcome to
post in the Meta site if you want to discuss wether your question is
on or off topic.
If a site dedicated to network engineering does not deal with homework questions why should Superuser deal those type of questions? We don't do people's homework for them, these types of questions, would be deleted by the community. If not deleted, it would at least get one vote, to be deleted.
Question 5: What is the difference between source based tree and shared core based tree?
You need to provide more context... bear in mind that programming
questions are off-topic here, and should be asked on Stack Overflow.
We agree send this question to Stackoverflow.
Question 6: Using co-located wireless access points to maximize client bandwidth [closed]
..also product recommendation requests are off-topic
We would vote to close this question for the same reason and the migration likely would be rejected by a moderator.
Queston 7: How can a Class B network be in the 10.0.0.0 space? [closed]
all homework/study questions are off-topic here...
See above responses with regards to homework questions.
Question 8: Site to Site VPN Theory [closed]
putting this on hold because 'resource recom' are off-topic. But you
could just tweak the wording a bit to make it ask for a high-level
outline of how VPNs work (and probably even better if you specify a
VPN type/product, eg, IPSEC)
This question should be improved and remain with you guys.
Question 9: Why is my Router's WAN IP different from public IP?
Is this about a home network? Home networking is off-topic here. You
can ask over on Super User
This questions seems to be within the scope of your website. This question is not actually been closed. It also is from 2015.
Question 10: HTTP 302 Redirect - Is this my problem? [closed]
isn't the question then: "Why is this AWS instance sending a 302 to
some queries?" ...and then that (configuring AWS) is off-topic here.
How you configure AWS, is not on topic at Superuser, it is well outside of our scope. Just because AWS is a computing environment does not mean its on topic.
Of course the real question, would have been on topic, I am neutral on a question like this.
So out of 10 questions, most of them closed by you, the only question that had any hope was the very first question. While I am not a moderator, and can't speak for anyone except myself, my opinion of each question I listed I feel is based on the contents of our own help center. I also realize that this is a small subset of your closed questions, and none of them might have been even questions, you would have migrated.
I tried to address the overall question you asked. You were wondering should question specifically not on topic at NE.SE but migrated here. I realize I would have to expand these 10 questions out to all the questions closed yesterday to get an honest snapshot of the type of questions closed.
