Just noticed that someone wrote me online in the game "Minecraft": "And how was your time off" since I had no internet before. Afterwards he wrote: "Do you want that again?" And then my internet was gone again. What can i do now
Restart your router.
Just restart your router or just wait for it to be harmless it won't be able to do much. You can of course return it DDOSn xD but mostly your internet will go away yourself… Fun fact can also show it because this was not done under your permission and is a crime in Germany.
But then he still has my IP address
No, as long as you don't mess around with the settings, they change after every restart
In the case of an advertisement, DDOSen is not the solution
Right, it was just satire.
Yes, but that's the Internet, everyone can take everything seriously here
Is it enough just to pull the router's power cord out for 1 minute and then back in? Just want to be on the safe side.
