Why does my client send like 1000 null bytes in the beginning of the connection to my local server? Seems like a waste of bandwith

or am i reading that wrong?
13:26
yea no i confirmed with tcpdump that looks like waste

the first three packets of client and server. It starts with a bunch of nullbytes from the client with a smol response from the server and yet another big chunk of nullbytes from the client. Whats the use of that?
ChillerDragon: I don't know if all the null bytes are intended, but some of them are for amplification protection

the problem with initial UDP packets is the potential for amplification attacks using spoofed attacks

since the server only responds to large packets (I think >512 bytes) with small packets (<50 bytes), the amplification factor is like 1/10, so no attacker is going to use that for attacking other servers
