When you create a zone on a DNS server, you will mainly use 4 types of DNS records :
To create an A (IPv4) or AAAA (IPv6) DNS record, select your forward lookup zone and right-click "New Host (A or AAAA)" in the right part of the window.
To create a A or AAAA record :
The A or AAAA record has been created.
Now, our "ns1.informatiweb.lan" domain points to the "10.0.0.101" IPv4 address.
And in the reverse lookup zone, the pointer indicates that the "10.0.0.101" IP address corresponds to the "ns1.informatiweb.lan" domain.
If you are hosting a website on your server, you may create a CNAME record to point the "www" subdomain to the same IP address as your root domain.
To do this, right-click "New Alias (CNAME)" in your forward lookup zone.
In our case, since our server is hosting our DNS zones, we will create a "dns-server-1" record for the demo.
Then, click on "Browse".
The list of your DNS servers is displayed.
Open the "Look in" list to select your forward lookup zone.
Then, select the DNS record to which the CNAME record should point.
Now, our "dns-server-1.informatiweb.lan" domain will point to the same IP address as the "ns1.informatiweb.lan" domain.
In the forward lookup zone, you will see the CNAME record.
But, no pointer will appear in the reverse lookup zone since CNAME records point to a "domain" and not an IP address.
When you install one or more mail servers in your network, it's important to indicate their presence in your DNS zone.
To do this, simply create one or more A or AAAA records, then create the MX records by right-clicking "New Mail Exchanger (MX)".
In our case, we have a single mail server for which we have created a "mail.informatiweb.lan" A record beforehand.
Now, specify the same domain for the MX record, then click "Browse" to select the A or AAAA record created previously (in our case : mail.informatiweb.lan).
Note : priority is only useful if you have multiple mail servers on your network.
If you have multiple mail servers in your network, you can use a different priority for each server to specify in which order the external mail servers will attempt to contact yours.
Warning : the mail server with the lowest number will have priority over the other mail servers. In other words, if you have a mail server with a priority of 10 and a 2nd with a priority of 20, the external mail servers will first try to contact the 1st server (with priority to 10), then the 2nd server (with priority to 20) if the 1st server doesn't respond.
To summarize, you could create the following records if you have 2 mail servers :
When you manage a DNS zone, you will mainly use the types of records mentioned above.
Nevertheless, be aware that there are many types of DNS records that may be able to serve you one day or another.
To access them, right-click in your forward lookup zone and click on "Other New Records".
Among the available DNS records types, you will find :
To test the configuration of your DNS server, you can use the nslookup command like this :
During your tests, we recommend that you clear the DNS cache on your computer before using this command. Thus, the answer obtained will be up to date.
To do this, first type this command :
Windows Server 1/15/2013
Windows Server 4/25/2018
Windows Server 5/11/2018
