Just a shower thought, Since many servers switch hosts , IP , ports and players have to add the server in lists again in my experience a server loses 30-50% of playerbase after a IP change. so instead of locking the server and changing name to alert users about IP change a server could just redirect user to another server when player joins (along with a prompt to add new IP or update existing server's IP in list).
Code:
Redirect(playerid,"192.168.1.1:7777")
