networking

hi,
i would like someone to help me about some stuff thing which is related to the networking computers.
actually i am student of university so i normally accesses one of the LABS in the campus. therefore i normally see all the computers are connected to each other. however what is interesting to me is that i want to access other computers which are surrounding me by my computers. then the problem goes to the command TRACERT because i can't identify whenever i type and follow host name-for instance say that i want to know all computers that using or to get ip addresses, it will bring a lot of ip addresses which i'm sure if those ip addresses are locally to the campus or outside of the country.

what i want to summarize is that i want to know the ip addresses of the other computers on the university's lab by using command prompt for TRACERT or any other command.

thanks so much indeed.

kind regards.

at a cmd prompt type: netstat -a -n

that will show all open connections and ports
