To add a DNS record to a DNS server, follow these steps:
1. Log in to the DNS server: You will need to have access to the DNS server to make changes.
1. Identify the zone: Determine in which zone you need to add the DNS record. Usually, this is the domain name of the website.
1. Choose the record type: Decide which type of DNS record you need to add, such as A record, MX record, CNAME record or NS record.
1. Create the record: Enter the required information, such as IP address or target domain name.
1. Save the record: Once you have entered all necessary information, save the record.
1. Wait for propagation: Changes may not take effect immediately due to DNS propagation. It may take up to 24-48 hours for the new DNS record to be available across the internet.
1. Verify the record: Use a command-line tool or online DNS lookup tool to verify the record has been added correctly.
