   print "Name = $name\n";
   print "Aliases = $aliases\n";
   print "Addrtype = $addrtype\n";
   print "Net = $net\n";
}
setnetent(1); # Rewind the database;
while ( ($name, $aliases, $addrtype, $net)  = getnetent() ) {
   print "Name = $name\n";
   print "Aliases = $aliases\n";
   print "Addrtype = $addrtype\n";
   print "Net = $net\n";
}
endnetent();  # Closes the database;

执行上述代码时，会产生以下结果 -

Name = default
Aliases = 
Addrtype = 2
Net = 0
Name = loopback
Aliases = 
Addrtype = 2
Net = 2130706432
Name = link-local
Aliases = 
Addrtype = 2
Net = 2851995648
Name = default
Aliases = 
Addrtype = 2
Net = 0
Name = loopback
Aliases = 
Addrtype = 2
Net = 2130706432
Name = link-local
Aliases = 
Addrtype = 2
Net = 2851995648
