Yes, you're right. I missed the Ethernet Header. The Ethernet Header would look like this: 0x45 00 00 34 08 3a 00 00 7e 06 00 00 10 0a 00 00 07 D4 04 00 00 7a 12 00 50 00 03 5c 00 01 05 00 00 37 6e 00 01 2d C8 00 17 45 54 48 52 20 43 4F 4D 50 55 54 45 52 0D 0A.

Sure, I can do that. The HR Hex for a simple UDP client using port 10.0.0.7 port 1234 to greet a server at 104.0.0.1 port 1234 with a "hello" message would look something like this: 0x45 00 00 21 08 3a 00 00 7e 06 00 00 10 0a 00 00 07 D4 04 00 00 7a 12 00 17 00 01 aa 00 00 48 65 6c 6c 6f 0d 0a. This would send the "hello" message to the server at the specified IP address and port.
