Migrate custom domain to new IP

Last updated on 23 Apr, 2025

Change the A records for an existing connected domain or subdomain

If you already have a domain connected with your BookingKoala account, please follow the guidelines to change the A records and verify the domain.

  1. Login to your domain's registrar account.

  2. Locate and open the domain's DNS settings page to edit them.  You may see a section called "Advanced DNS" or "Manage DNS settings".  

  3. Remove the A record with IP address 18.188.223.178

  4. Now add following two IPs in the A record for the domain or subdomain 

      162.159.141.169
      172.66.1.165


      Repeat following steps to add both IP addresses in A records.

  5. Record Type:

    • Enter or select "A" or "A record"

  6. Name:

    • For primary domains: Enter the @ symbol or leave the section blank if it says to leave the box empty to set up records for the primary domain. 

    • For other subdomains: Enter the subdomain's name/extension here.

      • For example, you would enter the word "bookings" here to create a subdomain called "bookings.yourbusinessname.com".  

  7. Data/IP Address:

    •  Add the IP address

  8. TTL

    • If you see this option when setting up the A record,  you use the host's default selection such as "Automatic", "3600", or "60 minutes".

  9. Click whichever option is offered to "Add", "Update", or "Save" your new/edited A record.

  10. (this step is applicable only if you are connecting the main domain but not the subdomain)
    Once you have added the A records for the domain, make sure all other A records are removed.

  11. Next, you will need to add CNAME for the www subdomain as shown in the below example, make sure that value for CNAME contains your domain only. For example, if your domain is mydomain.com then the value should be mydomain.com.
