-## Object Storage - Multipart Upload Overview
-
 [Multipart Uploads](/storage/object/api-cli/multipart-uploads/) allows you to upload large files (up to 5 TB) to the Object Storage platform in multiple parts. This allows faster, more flexible uploads.
 
 If you do not complete a multipart upload, all the uploaded parts will still be stored and counted as part of your storage usage. Multipart uploads can be aborted manually [via the API and CLI](/storage/object/api-cli/multipart-uploads/#aborting-a-multipart-upload) or automatically using a [Lifecycle rule](/storage/object/api-cli/lifecycle-rules-api/#setting-rules-for-incomplete-multipart-uploads).

 ## Installing BIND
 
-Install BIND and its related tools.
+1. Install the latest version of BIND 9.20 and related tools:
     ```
     apt-get install bind9 bind9utils bind9-doc dnsutils
     ```
+2. Verify the installed version:
+    ```
+    named -v
+    ```
+    The expected output should be:
+    ```
+    BIN 9.20.x
+    ```

 3. Create your zone file. A zone file must contain at least an SOA, an NS, and an A record or CNAME.
     ```
-    nano db.scw-domain.ml
+    sudo nano /etc/bind/db.example.com
     ```
 4. Paste the following:
     ```

+
+## Security and best Practices
+
+- Use `allow-transfer` and `allow-update` directives to limit who can query or modify your DNS zones.
+- Sign your zones using DNSSEC to protect against DNS spoofing and man-in-the-middle attacks.
+- Use `rndc` or log analysis tools to monitor DNS queries and server performance.

+## Conclusion
 
-You can try to resolve hostnames on both servers by typing `dig www.scw-domain.ml @ns1.scw-domain.ml` & `dig www.scw-domain.ml @ns2.scw-domain.ml`
+You have successfully configured a DNS server using BIND 9.20. You can now resolve domain names within your infrastructure or serve DNS queries to external clients.
 
-You should see in the answer section the following:
-```
-;; ANSWER SECTION:
-www.scw-domain.ml.	86400	IN	A	51.15.242.21
-```
