Use one of the DNS modules to lookup the A records. This will give you IP addresses which you can check against each other. Alas, this is far from fullproof: load sharing www servers via DNS will give you different IPs each time you lookup, and also a single server can serve many sites, all of them will have same ip (apache virtual names.) One step better is head information, but still not fullproof. Ultimately only full content comparison is 100% proof of content similarity or otherwise.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
