Yes you need a port as well. Same one as the one you have in your .CONF-file.
Example of my .CONF:
rpcuser=whateveryouwant
rpcpassword=x
rpcconnect=127.0.0.1
rpcallowip=192.168.1.*
rpcallowip=192.168.1.*
rpcport=9888
daemon=1
server=1
listen=1
gen=0
addnode=84.251.34.142:3232
addnode=84.251.34.142:2232
