Getting a part of IP address String
<p>If I have a IP address String like : 10.120.230.78 I would like to get 10.120. out of it</p>

<p>But the parts of the address can change from 1 tot 3 numbers as we all know ... </p>

<p>1.1.1.1 to 255.255.255.255 so ....</p>

<p>I believe you can use a pattern, but I don't have an idea how to.</p>

<p>Please, any suggestions would be welcome.</p>

<p>thx all</p>
