dnsjuice may offer different service tiers depending on the product and account type you are using. Some customers use entry-level service for simple DNS needs, while others choose paid plans for additional capacity, features, or service limits.
The best way to confirm what applies to your account is to review the product details shown during signup or in your client area. That will tell you which features, limits, and billing terms apply to your current plan.
If you are comparing options, pay attention to included query limits, available DNS features, and the renewal terms for the service you select.
