A-Records (Address Records) in DNS (Domain Name System) are used to map domain names to their corresponding IP addresses. These records are fundamental in DNS and enable users to enter easy-to-remember domain names (e.g., www.example.com) instead of complex numerical IP addresses (e.g., 192.0.2.1).
Situations for using A-Records:
Hosting a Website: When a new website is created, an A-Record is necessary to point to the server where the site's files are hosted.
Changing Hosting Providers: When moving a website to a new server, the A-Record needs to be updated to reflect the new IP address.
Subdomains: A-Records are also created for subdomains (e.g., blog.example.com) to point them to the correct servers.
Load Balancing: Sometimes, multiple A-Records are used for one domain to distribute the load across several servers.
Example of an A-Record in a DNS zone file:
example.com. IN A 192.0.2.1
www.example.com. IN A 192.0.2.1
How to specify an A-record
To manage DNS records use the DNS zone editor you need to go to:
Enter the section - Domains
Click Actions
Next, go to DNS Records (Regery)
To add a new entry you need:
Click - Add a new entry
Select record type A
Specify the required IP address
Save
IMPORTANT - If your domain points to other name servers, set up a DNS record on the platform your domain points to.
What Values to Use A-Records
Purpose | Value (Host) |
Domain | @ |
Subdomain | subdomain (e.g., subdomain.domain.tld) |
Wildcard | * |
FTP | ftp (e.g., ftp.domain.tld) |
Points
The Points to field is the IP address to which your domain should be pointed. You can only add IPv4 addresses. If you need to point the domain to IPv6, you should edit the AAAA record.
TTL
If you haven't received specific TTL requirements, use the default TTL value
How to Change or Delete a Record?
If you want to make changes or delete an existing record, go to the DNS zone editor of your domain and select the appropriate option:
Delete the record permanently.
Edit the record.
After making any changes to DNS records, it may take up to 24 hours for the changes to fully propagate.
