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 123-reg nameservers, you edit the zone at 123-reg.
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 123-reg 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 123-reg control panel.
- Go to the list of your domains. Look for Manage domains.
- Click the domain you want to edit.
- Find the DNS area. It is usually named Manage DNS or Advanced DNS. Click it.
- Look at the list of existing records. Note down the values.
- To add a record, pick the type, such as
A, and 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. - To change a record, click its edit icon, change the value and save.
- To remove a record, use its delete icon. Only delete what you are sure about.
- Save your changes.
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.
