Zone File Records<\/p>\n

The information as given below in a table are from a real domain and hosting.<\/p>\n

I just replaced the actual domain name with sahmed.com<\/p>\n

The domain is originally purchased at godaddy.com, and I created a hosting account for that domain (a real hosting account – not an add-on domain) under www.onlineservicescloud.com (i.e. I could act as hosting reseller).<\/p>\n

 <\/p>\n

Note<\/strong>:<\/p>\n

sahmed.com uses an A record<\/p>\n

 <\/p>\n

www.sahmed.com uses a CNAME record<\/p>\n

mail.sahmed.com uses a CNAME record<\/p>\n

ftp.sahmed.com uses a CNAME record<\/p>\n

 <\/p>\n

all other sub-domains used A records<\/p>\n

All these were created automatically as soon as I creating hosting account for the domain (I used WHM to create the hosting account)<\/p>\n

Yes, I did not mention the real IP address here.<\/p>\n

 <\/p>\n

A Record<\/strong>: Returns a 32-bit IPv4<\/a> address, most commonly used to map hostnames<\/a> to an IP address of the host<\/p>\n

CNAME Record:<\/strong> Alias of one name to another: the DNS lookup will continue by retrying the lookup with the new name<\/p>\n

 <\/p>\n

At GoDaddy, I provided NS1.ONLINESERVICESCLOUD.COM<\/span> and NS2.ONLINESERVICESCLOUD.COM as the DNS servers. Yes, the hosting account is created under onlineservicescloud.com. <\/span><\/p>\n

At GoDaddy domain forwarding is turned off. At GoDaddy 0 Sub-domain is forwarded.<\/span><\/p>\n
