<\/span><\/h3>\n\nFinding your MTU value can be done through various methods and tools. However, one of the most commonly used techniques involves using the Command Prompt on Windows or Terminal on macOS and Linux. Follow these steps to find your MTU value:<\/p>\n
1. Open the Command Prompt (Windows) or Terminal (macOS\/Linux).
\n2. Type the following command and press Enter (return): ping -f -l [packet size] [destination IP]<\/strong>. Replace [packet size] with a numeric value between 1400 and 1500 (start with the default 1472). [destination IP] should be the IP address of a reliable remote server or website (e.g., 8.8.8.8).
\n3. The result will show a line that says “Packet needs to be fragmented but the DF bit is set.”
\n4. Decrease the [packet size] value by 10 (e.g., from 1472 to 1462) and repeat step 2 until the result shows a different message, indicating that the packet was successfully transmitted.
\n5. Once you have a successful transmission, add 28 to the [packet size] value (to account for header size) to determine your MTU value.<\/p>\nFor example:<\/p>\n
ping -f -l 1462 8.8.8.8<\/strong> – This command may result in fragmentation.<\/p>\n<\/p>\n
ping -f -l 1452 8.8.8.8<\/strong> – This command may result in a successful transmission.<\/p>\nIn this case, the MTU value would be 1452 + 28 = 1480<\/strong>.<\/p>\n
