IPGuard — Protect your server from IP double logins
IPGuard is a simple and powerful plugin that prevents players from connecting simultaneously using different IP addresses.
When a player connects for the first time, their IP address is automatically saved. On future logins, if the IP is different, they will be denied access — preventing account sharing and improving overall security.

✅ Main Features

• Blocks login attempts if the IP differs from the saved one
  
  
• Self-unlink system with /unlinkip command
  
  
• Admins can unlink other players with /unlinkip <player>
  
  
• Multi-language support via an editable langs.yml file
  
  
• Stores IP data in ips.yml
  
  
• /debugip command to list all registered IPs (admin only)
