I have a dropdown list with different servers IP addresses in the www.example.com code.

<form>
    <select>
        <option value="0">Select your Server..</option>
        <option value="x.x.x.x">India</option>
        <option value="y.y.y.y">USA</option>
        <option value="z.z.z.z">UK</option>
    </select>
    <input type="submit" value="Submit" class="myButton">
</form>

However, when I select from the dropdown, the URL also changes to that particular IP address. Is there a way to mask the IP address in Javascript so that the URL www.example.com remains the same?
