What is DNS?
DNS (Domain Name System) is the system that converts domain names into IP addresses, so that computer networks can communicate with each other. When a user types a domain name into their browser, the DNS translates the domain name into an IP address and sends a request to the web server hosting the website. The web server then responds with the requested web page, which is displayed on the user’s browser. DNS is essential for the operation of the internet, making it easy for users to access websites without having to remember IP addresses.
What is Debian 7?
Debian is a free and open-source operating system that is widely used for web servers. Debian 7 is an older version of Debian that is still used by some web administrators. Although newer versions of Debian are available, some organizations prefer Debian 7 for its stability and predictability.

Konfigurasi DNS Server Debian 7
Step 1: Install the DNS server package
The first step in configuring DNS server Debian 7 is to install the DNS server package. This can be done by running the following command:
$ sudo apt-get update
$ sudo apt-get install bind9
This will install the bind9 package, which is the DNS server software.
Step 2: Configure the DNS zone file
The next step is to configure the DNS zone file. This file contains the information about the DNS domain, including its IP address and other settings. The DNS zone file can be edited using a text editor such as nano or vi. The following is an example of a DNS zone file:
$sudo nano /etc/bind/named.conf.local
zone "example.com" {
type master;
file "/etc/bind/db.example.com";
};
The above example creates a DNS zone file for the domain example.com. The zone file is located at /etc/bind/db.example.com. You can replace example.com with your own domain name.
Step 3: Configure the DNS records
The next step is to configure the DNS records. This is done by editing the DNS zone file. The following is an example of a DNS zone file:
$sudo nano /etc/bind/db.example.com
$TTL86400
@INSOAns1.example.com. admin.example.com. (
2001062501 ; serial
21600; refresh after 6 hours
3600; retry after 1 hour
604800; expire after 1 week
86400 ); minimum TTL of 1 day
; Name servers
INNSns1.example.com.
INNSns2.example.com.
; A records for name servers
ns1INA192.168.1.1
ns2INA192.168.1.2
; Other A records
INA192.168.1.3
INA192.168.1.4
This example creates DNS records for the domain example.com. The SOA record contains information about the primary DNS server and the email address of the administrator. The NS records specify the name servers for the domain. The A records specify the IP addresses of the domain and subdomains.
Step 4: Restart the DNS server
Once the DNS zone file and DNS records have been configured, the DNS server needs to be restarted for the changes to take effect. This can be done by running the following command:
$sudo service bind9 restart
Step 5: Test the DNS server
The final step is to test the DNS server to ensure that it is working correctly. This can be done by using the dig command. For example, to look up the IP address of the domain example.com, run the following command:
$dig example.com
If the DNS server is working correctly, dig should return the IP address of the domain.
Frequently Asked Questions (FAQs)
What is the difference between a DNS server and a web server?
A DNS server is responsible for converting domain names into IP addresses, while a web server is responsible for serving web pages to users who request them. Although both types of servers are essential for website operations, they have different functions.
What is the purpose of a DNS zone file?
A DNS zone file contains the information about the DNS domain, including its IP address and other settings. The DNS server uses this information to resolve domain names into IP addresses and route network traffic.
What is the advantage of using an open-source operating system like Debian?
Open-source operating systems like Debian are free to use and can be customized to meet specific needs. They also tend to be more stable and secure than proprietary operating systems.
How often should I update my DNS zone file?
It is recommended to update your DNS zone file whenever changes are made to your network topology or domain settings. This ensures that the DNS server has the most up-to-date information and can route network traffic correctly.
How do I know if my DNS server is working correctly?
You can test your DNS server by using the dig command to look up the IP address of a domain. If dig returns the correct IP address, then your DNS server is working correctly.
Can I use Debian 7 for a large-scale website with high traffic?
While Debian 7 can be used for a large-scale website with high traffic, newer operating systems may be better suited for such applications. Debian 7 is known for its stability, but may not have the same level of performance and features as newer operating systems.
How do I optimize website performance with DNS server Debian 7?
One way to optimize website performance with DNS server Debian 7 is to use a content delivery network (CDN) to distribute website content to servers around the world. This can improve website speed and reduce server load.
How do I troubleshoot DNS server Debian 7 issues?
If you are experiencing issues with your DNS server Debian 7, you can check the DNS server logs for error messages. You can also use tools like dig and nslookup to diagnose DNS issues.
Can I use DNS server Debian 7 with a Windows-based network?
Yes, DNS server Debian 7 can be used with a Windows-based network. However, some configuration may be required to ensure compatibility.
What is the difference between a primary DNS server and a secondary DNS server?
A primary DNS server is the main DNS server for a domain, while a secondary DNS server is a backup DNS server that can provide redundancy in case the primary DNS server fails.
What is the role of the SOA record in a DNS zone file?
The SOA record in a DNS zone file contains information about the primary DNS server and the email address of the administrator. It also specifies the serial number of the zone file, which is used to ensure that changes to the DNS zone file are propagated correctly.
How do I add a subdomain to my DNS server Debian 7?
To add a subdomain to your DNS server Debian 7, you can create a new DNS zone file for the subdomain and configure the necessary DNS records. You can then restart the DNS server to apply the changes.
What is the TTL setting in a DNS zone file?
The TTL (Time to Live) setting in a DNS zone file specifies how long DNS records should be cached by other DNS servers. A shorter TTL can improve website performance by reducing the time it takes for DNS changes to propagate.
What is the purpose of the NS record in a DNS zone file?
The NS (Name Server) record in a DNS zone file specifies the name servers for the domain. This tells other DNS servers where to find the authoritative DNS server for the domain.
How do I configure reverse DNS lookup with DNS server Debian 7?
To configure reverse DNS lookup with DNS server Debian 7, you can create a new DNS zone file for the IP address range and configure the necessary PTR records. You can then restart the DNS server to apply the changes.
