I am an AWS user and earlier I was hosting my website on AWS S3. I recently tried the zohosites.com and redesigned the website with it. I have added the CNAME to AWS Route 53 and i could easily host my website with zohosite. 

The only problem i'm facing is that i can only access my website using www, e.g https://www.mydomain.com but when I try going to the website without www, i.e. only https://mydomain.com, It just doesnt open. 

I think I need to add an "A" Record to it but I don't know the ip address that i should redirect it to.

Any help would be great. I can see my website with "www", but cannot without it.!!
