Custom domain settings provide you with possibility to completely hide inndesk.com URL and use custom domain instead. For example www.your-hotel.com. To do this, you need to register your own domain using a 3rd-party domain provider like GoDaddy, 1and1 or any other. Then you need to follow these 3 steps.
Using control panel provided by the domain provider you need to locate DNS Manager. Create an A Record of your domain without the www which will point to our IP Address (184.108.40.206).
Using control panel provided by the domain provider you need to locate DNS Manager. Here should be CNAMES (Aliases) box where you will be able to create a CNAME record that points your domain to us. CNAME for www should point to your subdomain on inndesk.com. For example hotel.inndesk.com.
Note: Some DNS managers may require you to put extra dot (.) after your subdomain. For example: 'hotel.inndesk.com.'
On completing two steps above, just type your custom domain to custom domain field in Settings -> Custom Domain, such as www.your-hotel.com and everything is ready to go. Note that sometimes it can take up to 48 hours for all the DNS changes to become refreshed across the whole internet.
