Connecting domains to websites is a common issue for domain providers. If you contact your provider for support, there are in general two important changes you want the ask your provider about. First, point your A record to the Booking WebDirect IP address 18.104.22.168 and second redirect the “www” CNAME record to “suite-sites.booking.com”.
You can use the following template to contact your provider to request these changes:
I am reaching out to connect my domain (INSERT YOUR DOMAIN HERE) which I registered with your service to my website. In order to set this up correctly I need to change the A records for my root domain to point to 22.214.171.124. In addition I’d like to create a redirect for the “www” CNAME record to “suite-sites.booking.com”. Please not that I am not requesting a transfer of my domain. I want to continue to manage it with your service.
Please kindly make the required changes to my account for me.
