Enter a Hostname or IP Address for the address to test the MTU Path.
The goal for this tool is to figure out the largest possible packet that can be sent from this server to the destination.
It works by sending packets of varying sizes with the Don't Fragment (DF) bit set in the IP header.
A standard MTU size is 1500 Bytes. If the connection from source to destination can't handle a MTU size of 1500 Bytes then the connection can be fragmented.
This tools uses ICMP to discover the largest packet, but this may be blocked by some routers and then the test will fail.
