Use "q id" in the chat room What is shown is its real IP I wrote "use big5" because some BBS systems support big5 code browsing, but cannot recognize the IP used to log in like this. A typical example is Fudan Sun Moon Guanghua Station. Try telnet 202.120.224.9 2323 and choose bb5 to log in. At this time, the system cannot recognize the IP address and displays [unknown]. Tsinghua SMTH also supports big5 code browsing. Select bb5 to log in, but the system can recognize the IP logged in like this. Jiaotong University Drinking Water Siyuan Station also provided this service port 2323, but it is not supported now. In fact, a better way is to shuttle. Shuttle from other BBS to here. What is displayed is the IP address of the shuttle BBS. There must be other ways to display or block IP, welcome to add and discuss.
