If you already have a domain name, log into your domain registrar (i.e. GoDaddy, domain.com, eNom, NameCheap etc...) and look to "Edit" the DNS records of your domain name.
You need to "Create" or "Edit" 2 records:
1) "A" - Host Records:
Once you get to the Edit DNS screen, find the "A" host record value for the root domain (yourrestaurant.com), the IP will probably be xxx.xxx.xxx.xxx change this value to: 198.11.244.34
Sample screen shot of what this looks like with GoDaddy, other registrars will have a different screen, but similar records.
2) "CNAME" / Alias Records:
A CNAME record for "www" can already exist in your DNS settings or you will have to create one. The CNAME record will point your subdomain of "www" to our servers. For example: "www.yourrestaurant.com". For this CNAME record, the points to value should be: restaurants.247waiter.com
