How to understand what these commands are in hex?

Question

Computer networks

Trying to figure out what is being sent to a socket connection

sock = socks.socksocket()
sock.send("\x12\x00/\x0c122.19.155.85\x03\xe3\x02\x0b\x00\t") #mc
sock.send("\x13\x00\x05\r98.42.42.98c\xdd\x01\x01\x00") #ping

Are these some random commands or not? Where can I read about it or how to google it?
TCP headers, IP do not fit like.
