 +# ❓ Extra Explanations 
 + 
 +- **Why pick a high number at the end?**   
 +  Routers usually give IPs automatically starting from low numbers. Picking `.200` or higher avoids conflicts with phones, laptops, or smart TVs.   
 + 
 +- **What if my network uses a different range?**   
 +  Check your current IP. Use the same first three numbers and pick a high number at the end outside the DHCP range.   
 + 
 +- **What happens if two devices have the same IP?**   
 +  Both devices will lose internet or get strange problems.  
  
 +- **Why only UDP?**  
 +  NFS Underground only needs UDP for online play. TCP is not used.
