Which is the least Internet Explorer version to use file shtml??

[TDK22]

I'm using a file with shtm extension on my Internet information Server 4.0. I use this:
<SCRIPT LANGUAGE=&quot;JavaScript&quot;>
//var ip = '172.32.6.105';
var ip = '<!--#echo var=&quot;REMOTE_ADDR&quot;-->';
document.write('<input type=text name=&quot;TEM_IP&quot; size=20 value=&quot;'+ip+'&quot;>');
</script>

I've got problem with Internet Explorer 5.0, it function only with Internet Explorer 5.5.
Is it true??

thanks in advance for your help
bye.
