DNS ZONE tutorials

We have 5 zones

  • Primary Zone

  • Secondary Zone

  • Stub Zone

  • AD-I (Active Directory Integrated Zone)

  • Conditional Forwarding

 

1) Primary Zone:-

  • a Primary zone file is master copy of zone. This zone is stores records that are writable copy. That is it can Read/Write data and it gets updated when data gets modified.

 

2) Secondary Zone:

  • is a copy of Primary Zone. It is Read-Only copy and it gets updated when Primary Zone server send copy of Zone file to Secondary Server. Select a secondary zone to copy read-only data from another server. For e.g. you windows server can be secondary server to a non-windows server or vice versa. Secondary zone server helps to

  • a) Fault tolerance b) Load Balancing c) Reduce name resolution traffic over WAN link

 

3) Stub Zone:

  • list authoritative name server for a zone so that DNS servers hosting a parent zone are aware of authoritative DNS server for the related child zone. It will store information about another DNS server. However it won’t be full zone transfer. It will be something called “mini” zone transfer. It will keep partial records of stub zone. Stub zones are dynamic. Any changes made will be automatically set.

 

4) DNS + Active Directory Integrated Zone

  • Advantages of DNS + (AD-I) Active Directory Integrated Zones are

  • Zone updates are secure, because AD replication is secure. In standard DNS we have update from primary to secondary. Those update are made on wire by clear text which is not secure.

  • Better fault tolerance, in standard DNS only Primary DNS server is Read/Write copy where as Secondary DNS are only Read copy. Where as in AD, all DC are Read/Write copy so all DNS + AD-I are Read/Write copy

  • No more ‘Zone transfer’, because whatever changes are made to DNS database, those changes are replicated to other DNS with AD replication

 

5) Conditional Forwarding: -

  • Normally when you forward DNS query, You can specify which DNS server to contact depends upon query. Lets say when we make query to surf www. xyz. com in our browser, it will go to our ISP DNS server. ISP DNS server may set conditional forwarding record like to query www. Xyz . com go to DNS server of xyz.com. for www. Abc. Com go to DNS server of abc. Com for everything else go to TRL DNS server.

  • Configuration of conditional forwarding is static and it must be updated when any changes to forwarders are made.
