Multiple top-level domain Analytics tracking

What is the correct way to track multiple domains to the one site?

I have domain.com,
domain.ie,
and domain.co.uk.

Do I track this with one account and then 3 different profiles for each domain? This mean I have 3 tracking codes on the page?

I this correct way. I only have one site but i want to track the traffic from the different domains

Yes, I can track visits on these three with one account using different profiles for each domain. You need to create a google analytics a/c and add your sites there.

Ok so just make sure. I can then insert the 3 scripts in my head like so. With the first script domain set?
_gaq.push([‘_setDomainName’, ‘domain.com’]);
or should they all be set to none?

<script type=“text/javascript”>

var _gaq = _gaq || ;
_gaq.push([‘_setAccount’, ‘UA-xxxxxxx-1’]);
_gaq.push([‘_setDomainName’, ‘domain.com’]);
_gaq.push([‘_setAllowHash’, ‘false’]);
_gaq.push([‘_setAllowLinker’, true]);
_gaq.push([‘_trackPageview’]);

(function() {
var ga = document.createElement(‘script’); ga.type = ‘text/javascript’; ga.async = true;
ga.src = (‘https:’ == document.location.protocol ? ‘https://ssl’ : ‘http://www’) + ‘.google-analytics.com/ga.js’;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(ga, s);
})();

</script>
<script type=“text/javascript”>

var _gaq = _gaq || ;
_gaq.push([‘_setAccount’, ‘UA-xxxxxxx-2’]);
_gaq.push([‘_setDomainName’, ‘none’]);
_gaq.push([‘_setAllowLinker’, true]);
_gaq.push([‘_trackPageview’]);

(function() {
var ga = document.createElement(‘script’); ga.type = ‘text/javascript’; ga.async = true;
ga.src = (‘https:’ == document.location.protocol ? ‘https://ssl’ : ‘http://www’) + ‘.google-analytics.com/ga.js’;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(ga, s);
})();
