That’s a local lan address.
Unless you can provide significant evidence of what’s wrong, I’m going to
- close this thread. and
- if further threads get made without actionable logs, versions etc, ban your forum account under the suspicion of trolling and wasting our time.
What we need in order to help is, versions of software used, Minecraft, Forge (if present), Sponge version used, a list of mods, your logs, and a Description of what’s wrong. this is your final warning.
Feel free to use Google translate, or post in your native language if necessary.
