Wireshark provides an immense amount of background information and tries to parse as much as possible out of a frame.
The TCP port 2628 is used for dictionary service (RFC 2229) which seems to be running on 202.85.215.42. Of course, Wireshark can't really tell which application-layer protocol is used, it just guesses from the port number.
