Do subdomains need to be defined through domain registrar?
- by Johnny
I have bought a new domain name from GoDaddy. Let's say it is abcd.com.
On GoDaddy's DNS Managing page, I changed A(Host) part to
@ = 74.125.232.215
which is www.google.co.uk's IP address.
Now if I type www.abcd.com, it directly goes to www.google.co.uk.
But if I type http://test.abcd.com, it cannot be loaded.
Do I need to define every subdomain through GoDaddy? Is this how it works?
P.S. Amazon EC2 directly generates a subdomain for users to reach
their virtual PCs. It cannot be domain registrar dependant.
P.S.2. Same question for using "www2" at the start of url.
