"DNS Management" lets you modify DNS record for your domain. This allows you to control which ISP or Hosting company is designated to maintain the name servers for your domain name information.
Domain Name Servers hold the information about how to reach your domain name. Every domain name has one primary nameserver, and at least one secondary nameserver. Secondary nameservers get their information directly from the primary nameserver, and check it periodically for updates. Domain Direct provides two secondary nameservers for each domain.
