 Arguments:

=head3   getIPaddress 
 Description:    
        Used by DFM related functions. When getting the IPs for CECs' FSPs, or
        getting the IPs for Frames' BPAs. And the IPs order is A-0,A-1,B-0,B-1.
	When getting the IP for one FSP or one BPA, if the $nodetocheck it one IP,
	it will return the IP immediately; if not, it will get the IP of the FSP or BPA.
                         
 Arguments:
    $request: Because getIPaddress() is always used for one node after the process fork. Avoiding to 
              access the DB for each node in the subprocess, we should collect the attributs before
	      process fork, and put the attributes in the $request variable. For the getIpaddress().
              The $request parameter should include the ppc hash which mapping the CEC->FSPs and 
              Frames->BPAs, and vpd hash the fsp->side and the bpa->side.
    $type:    the type of the $nodetocheck
    $nodetocheck:  Node name,  only one node at a time.
    $port:   if the $nodetocheck is a fsp or bpa, it will be usde.
    Returns: ip address(s)
    Globals:
        none
