Well, a quick glance at perldoc IO::Socket::INET told me rather directly: 

           In addition to the key-value pairs accepted by the
           IO::Socket manpage, IO::Socket::INET provides.

               PeerAddr    Remote host address          <hostname>[:<p
+ort>]
               PeerHost    Synonym for PeerAddr
               PeerPort    Remote port or service       <service>[(<no
+>)] | <no>
               LocalAddr   Local host bind address      hostname[:port
+]
               LocalHost   Synonym for LocalAddr
               LocalPort   Local host bind port         <service>[(<no
+>)] | <no>
               Proto       Protocol name (or number)    "tcp" | "udp" 
+| ...
               Type        Socket type                  SOCK_STREAM | 
+SOCK_DGRAM | ...
               Listen      Queue size for listen
               Reuse       Set SO_REUSEADDR before binding
               Timeout     Timeout value for various operations

See LocalPort there? That's your baby. LocalPort => 998, for example.

So, there's your answer in black and white.

However, be sure to see my other post on this on why this is a false sense of security.
