A question about sending UDP packets. From what I’ve read, the maximum size UDP packet that can be sent is 512 bytes. However, being that MTU can carry 576 bytes, and an IPv4 header is 20 bytes, and the UDP header 8 bytes. Aren’t there 548 bytes still available?
Therefore,is it possible to send packets of up to 548 without fragmentation or is there a specific reason why 512 is the limit?
