To point the domain to your VPS IP, you will need to edit the zone file at your domain registrar. To edit the zone file, you will be using the default Name servers provided by your domain registrar.
Step 1: Login to your Garanntor Client Area
Step 2: click on "Domains"
Step 3: In "Domains" Page, on the relevant domain click the "settings icon", then click on "DNS Management"
Step 4: On the DNS Management page, you would need to Edit your domain DNS Record to point to your server IP as shown in image below.
Hostname = www | Record Type = A | Address = "Insert IP"
Hostname = @ | Record Type = A | Address = "Insert IP"
Hostname = * | Record Type = A | Address = "Insert IP"
Hostname = @ | Record Type = NS | Address = NS5.GARANNTOR.NET
Hostname = @ | Record Type = NS | Address = NS6.GARANNTOR.NET
Note: Replace the IP above with your VPS or Server IP and delete other default records.
Step 6: Make sure you click on "Save Changes" before exiting to save any changes that you have made.
Note: Any DNS changes you make will require propagation, which typically takes 4 to 8 hours for individual DNS record changes. It takes 24 to 48 hours for name server changes to propagate (update) worldwide.
