You can manage A record from the DNS Zone Editor.
A (Host) section provides you with these buttons:
- Button to edit A record
- Button for deleting your A record completely
- Button for adding a new A record
How to add an A record?
If you are adding A records for your domain, insert @ as host.
If you are adding A records for your subdomain, insert the subdomain’s name as a host, for example for subdomain support.hostinger.com you should insert support as a host.
If you wish to add wildcard A record for all of your subdomain, insert * as host.
If you want to access your account via FTP using ftp.youdomain.tld as a host, you need also a record with ftp host and your account’s IP as a value.
