<span style="color: #000000">An authoritative DNS server group is a collection of primary DNS servers and secondary DNS servers. After you create an authoritative DNS server group, you can then assign it to serve authoritative forward-mapping and reverse-mapping zones. You cannot delete an authoritative DNS server group if the group is assigned to a zone.</span>

<span style="color: #000000">When creating a DNS Server Group the usage of Primary or Secondary DNS servers depends on the type of target zone the DNS Server Group will be assigned to. To use a DNS Server Group with Secondary zones, both primary master DNS Servers and Secondary DNS servers must be configured. To use a DNS Server Group with Primary zones, only Secondary DNS servers should be configured.</span>
