DNS / SubDomain

@puleen:

Folks,

Thanks in advance for your help. I want to setup a domain such as: who.is.this.com and I already have "this.com". In order to do this do I need to create 2 A records? One for is.this.com and Second for who.is.this.com? Or do I just create One A record for who.is.this.com?

Thanks,
If you've got an A record for this.com. (yes you need the trailing . ) You just need one for

this

Then another one for

is.this

So it would look like

this.com.

is

who.is

Cheers
