Hi. Sometimes it can be helpful to find out the own ip-addresses. This is a way to do it with the help of an undocumented feature of gethostbyname. HTH
#!/usr/bin/perl  
 
use Socket;  
use strict;  
 
sub ShowIPLocalInfo  
{  
   my @hostent = gethostbyname(undef) or return 0;  
 
   print "name:     ",shift @hostent,"\n"; # the name
   print "alias:    ",shift @hostent,"\n"; # not always available
   print "addrtype: ",shift @hostent,"\n";  
   print "length:   ",shift @hostent,"\n";  
 
   print "\nOwn Ip-Addresses:\r\n";  
   print "\t",inet_ntoa($_), "\n" foreach (@hostent);  
}  
 
ShowIPLocalInfo();
