Some problems I see without running the code:

You read from the IPS handle, but don't remove the line endings. Add a chomp as first command of the while loop.
3.3.3.* is neither a valid IPv4 address nor a valid host name, thus Net::Telnet will never be able to connect. You need to expand * in your code.
The same applies to 3.3.9.*.
I don't see any method calls for the $telnet object (open, getline, close).
Confusing indent.
Missing error checks at least for open OUT
You are opening OUT more than once.
From the error messages, there seems to be a problem with your input file, but the error messages should not happen with the code you posted. Did you post the code that actually generated the error messages?

Apart from that, I think that a simple nmap port scan should do the job, you don't need Perl for that.
