What is a DNS zone?
DNS is like a phone book for the internet. It turns a website name into a number that computers understand. A DNS zone is the page of that phone book that belongs to your domain. It holds small entries called records. Each record says where something goes, such as your website or your email.
You edit the zone where your domain's nameservers point. Nameservers are the computers that hold the zone. If your domain uses One.com nameservers, you edit the zone at One.com.
Warning: A wrong record can take your website or email offline. Write down the old values before you change anything.
Before you start
- Have your One.com login ready.
- Find the values you need to add. For Hostvento hosting, the server IP address is in your welcome email. If you cannot find it, ask Hostvento support.
Steps
- Log in to your One.com control panel.
- Open the Domains section.
- Find your domain in the list and open its settings. Look for a menu icon or a Manage button.
- Choose DNS settings.
- Read the existing records and note their values.
- To add a record, choose the type you need. Fill in the host name and the value. An A record links a name to an IP address. A CNAME record links one name to another name. An MX record tells the world where email goes.
- Click Save or Add.
- To change a record, use its edit option and save.
- To delete a record, use its delete option. Only delete what you are sure about.
Leave the host field empty when you mean the bare domain, such as example.com. Check that the domain uses One.com nameservers. If another company holds them, edit the zone there.
After the change
DNS changes do not show at once. They can take from a few minutes to some hours to spread. This waiting time is called propagation. Clear your browser cache and test again later.
