It's better to cast it to HttpContextBase, this way you can mock and test it more easily

public string GetUserIp(HttpRequestMessage request)
{
    if (request.Properties.ContainsKey("MS_HttpContext"))
    {
        var ctx = request.Properties["MS_HttpContext"] as HttpContextBase;
        if (ctx != null)
        {
            return ctx.Request.UserHostAddress;
        }
    }

    return null;
}
