Now there are two models for purchasing and renewing your Bulk DNS Service. You can now add service in blocks of up to 1,000 domains. In addition, you can add additional service prorated to your current expiration, or grossed up to a year from the present. In addition, you can renew your service either strictly by its current expiration date, or by having a "rolling" expiration date a year from the present date. Managing both your domains and your budget has never been easier. We're very pleased to offer you the most choices in DNS management.
