help

can someone help me?

So i always use emummc and in airplane mode, but today I wanted to check if I have dns properly. I downloaded the 90 dns tester, and when i put my wifi and used the app, everything appeared as unblocked. I quickly went back to airplane. The thing is, I am going to get banned by this? I have exophere blocking my ID, and it seems that I have default.txt on my atmosphere/hosts. So I truly don't know why it appeared as "unblocked" It seems it's more safer to use "emummc txt" instead. But I also tried to do it but, it didn't worked when I try to connect to my internet again.

Thanks!
