To put it simple, you can understand DNS forwarding as a method for DNS server to resolve a query by “asking for a help” from another DNS server. It is supported by on Windows DNS server, including Windows Server 2012 R2. The default behaviour is that Windows DNS Server will forward query that it cannot resolve […]
Stub zone is one of the way to forward DNS query for a specific zone to another DNS server where the zone resides (the Master server). Stub zone is similar to Secondary zone, but instead of creating duplicate of all records, it keeps only the information of SOA and NS record from the Master. The […]
Primary zone is a zone that can be updated directly on the DNS server where the zone resides. This means administrator can do any operations in the primary zone including modify, delete, and create DNS record. When DNS Server role is configured as part of Active Directory role configuration, Windows already configure a primary zone […]
When adding a DNS zone, there is an option to create secondary zone. A secondary zone is basically a replica of zone from another existing DNS server in the network. The other server which is being replicated is called the Master. Any changes on the Master applies to the secondary zone as well, but not […]
Conditional forwarding is another method of resolving external names by forwarding DNS query to another DNS server (or called the Forwarder). Conditional forwarding is different with regular DNS forwarding. In regular DNS forwarding the server will forward all queries that it cannot resolve to the Forwarder, but in conditional forwarding the server will only forward […]
You may have built DNS server to resolve names in your internal network, but you will still need to resolve external names. If you install DNS server role on Windows Server, it will perform query forwarding by default and therefore you can have external name resolution. This forwarding can be to a specific DNS server […]
Host record or A-record is a type of DNS record. Host A record serves the basic function of DNS server which is name-to-IP address mapping. It is the most common DNS record type and exists in the forward lookup zone as a static or dynamic record. Usually, an administrator manages the A record in enterprise […]
