I read a web page about networking and it mentioned that there could be up to 33 million network services in a Class C Network. I was puzzled and started using a calculator to figure it out.
No . of usable IP addresses = 253
No. of TCP Port + UDP port per IP address = 65535
Total number of available network services = 253 x 2 x 65535 = 33.16 million
This is the theoritical situation. In reality, most of the reliable Internet service can not be relied upon UDP. I would therefore better say there could only be 16 .5 million network services in a Class C network.
