SETTING UP A CONDITIONAL FORWARDER IN DNS

  A Forwarder is a DNS Server to which other DNS Server forward queries.

Types of Forwarders
  o    Standard
  o   Conditional

Conditional Forwarder: A conditional forwarder is a DNS server on a network that is used to forward DNS queries according to the DNS domain name in the query. For example, a DNS server can be configured to forward all the queries it receives for names ending with widgets.example.com to the IP address of a specific DNS server or to the IP addresses of multiple DNS servers.

Below figure shows how conditional forwarder is working.

Setting up a Conditional Forwarder:

1. Start -> Administrative Tools -> DNS

2. Right Click Conditional Forwarders -> Select New Conditional Forwarder.

3. Type the Condition and IP of appropriate DNS Server, Then Click OK

Eg: Here i have given infotech.com as my condition, If any query which is looking for infotech domain then the query will pass to 192.168.5.2 DNS Server.

SETTING UP A STANDARD FORWARDER IN DNS

  A Forwarder is a DNS Server to which other DNS Server forward queries.

          Types of Forwarders

  o    Standard

  o   Conditional

• Standard Forwarder: Standard Forwarder is a server that passes the information to other DNS Server, if it doesn't know the answer.

Below figure shows how standard forwarder is working. 

1. Start -> Administrative Tools -> DNS

2. Right Click DNS Server (BG-DC2-2k8) -> Click Properties.

3. Click Forwarder and Click Edit.

     4. Type  the appropriate IP address of DNS Server which you  want to make it as Standard DNSServer.

5. Apply and OK

Configuring IPv4 and IPv6 Settings Manually from the Command Prompt

                    'Netsh' utility will help to assign an IP configuration to a connection from the command prompt.To assign a static IPv4 address and subnet mask to a connection from the command prompt,type the following, where Connection_Name is the name of the connection (such as Local Area Connection), Address is the IPv4 address, and Subnet_Mask is the subnet mask.

netsh interface ip set address "Connection_Name" static Address Subnet_Mask

For example, to set the IPv4 address of the Local Area Connection to 192.168.33.5 with a subnet mask of 255.255.255.0, you would type the following:

netsh interface ip set address "local area connection" static 192.168.33.5 255.255.255.0 

If you also want to define a default gateway along with the IPv4 configuration, you can add that information to the end of the command. For example, to configure the same IPv4 address for the local area connection with a default gateway of 192.168.33.1, type the following:


netsh interface ip set address "local area connection" static 192.168.33.5 255.255.255.0 192.168.33.1


To assign a static IPv6 address to a connection from the command prompt, type the following, where Connection_Name is the name of the connection and Address is the IPv6 address.


netsh interface ipv6 set address "Connection_Name" Address

For example, to assign an address of 2001:db8:290c:1291::1 to the Local Area Connection (leaving the default subnet prefix of 64), type the following:

netsh interface ipv6 set address "Local Area Connection" 2001:db8:290c:1291::1
