<p>Now let&#8217;s talk about range selection. Suppose you have 1000 servers in group &#8216;datacenter&#8217;, but only want to target one at a time. This is also easy:</p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>ansible webservers<span class="o">[</span>0-100<span class="o">]</span> -m <span class="nb">command</span> -a <span class="s2">&quot;/bin/foo xyz&quot;</span>
<span class="nv">$ </span>ansible webservers<span class="o">[</span>101-200<span class="o">]</span> -m <span class="nb">command</span> -a <span class="s2">&quot;/bin/foo xyz&quot;</span>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>ansible webservers<span class="o">[</span>0-99<span class="o">]</span> -m <span class="nb">command</span> -a <span class="s2">&quot;/bin/foo xyz&quot;</span>
<span class="nv">$ </span>ansible webservers<span class="o">[</span>100-199<span class="o">]</span> -m <span class="nb">command</span> -a <span class="s2">&quot;/bin/foo xyz&quot;</span>
</pre></div>
</div>
<p>This will select the first 100, then the second 100, host entries in the webservers group. (It does not matter
what their names or IP addresses are).</p>
<p>Both of these methods can be used at the same time, and ranges can also be passed to the &#8211;limit parameter.</p>
