connectTo is not a web browser, but low level TCP/IP; it wants a hostname,
and only a hostname.  If you wanted to write a web browser or HTTP fetch
utility, you would connectTo the host on port 80 and then conduct an HTTP
exchange to GET /ip.

There are higher level libraries if you want to use HTTP without writing it
yourself.
