title: How to find the largest UDP packet I can send without fragmenting?
body: <p>I need to know what the largest UDP packet I can send to another computer is without fragmentation.</p>
  
  <p>This size is commonly known as the MTU (Maximum Transmission Unit). Supposedly, between 2 computers, will be many routers and modems that may have different MTUs. </p>
  
  <p>I read that the TCP implementation in windows automatically finds the maximum MTU in a path.</p>
  
  <p>I was also experimenting, and I found out that the maximum MTU from my computer to a server was 57712 bytes+header. Anything above that was discarded. My computer is on a LAN, isn't the MTU supposed to be around 1500 bytes?</p>
