The following describes the DNS deployment roles that you can configure in Address Manager.
|Primary||Deploys files and settings to create a DNS primary server.|
|Hidden Primary||Deploys files and settings to create a DNS primary, but without name server and glue records, thus hiding the server from DNS queries.|
|Secondary||Deploys files and settings to create a DNS secondary server.|
|Stealth Secondary||Deploys files and settings to create a DNS secondary, but without name server and glue records, thus hiding the server from DNS queries.|
|Forwarder||Deploys a forwarding zone in BIND, or conditional forwarding in Microsoft DNS, to forward queries for a specific zone to one or more DNS servers. Forwarding requires that recursion be enabled; recursion is automatically enabled when you select the Forwarder role. Use this role with external servers. For instructions on how to create an external server, refer to Adding Other DNS Servers.|
|Stub||A stub zone deploys a zone that contains only
name server records used to identify the authoritative DNS
servers for that zone. DNS lookups to a stub zone will return
the name server and corresponding host records, which will then
result in a separate query to the name servers for the host in
Stub zones are similar to secondary zones, where it gathers the record data from a designated server. However, stub zones are different from secondary zones in two ways:
Use stub zones to resolve names between separate DNS namespaces. For example, you might use this type of zone to resolve names for clients in separate namespaces after a corporate merger. In Address Manager, this zone type is often used with external servers, where the external server represents the authoritative primary. For instructions on how to create an external server, refer to Adding Other DNS Servers.
|Recursion||Used when creating a caching-only DNS server that accepts recursive queries, but doesn't host any zones. This role is available only at the view level. To use this role, you must also set Allow Query and Allow Query Cache DNS Deployment Options at the view level.|
|None||Clears all data from the server to which it's applied.|
