How can you ping a Domain name?
I think you have to redesign your naming system.
Hi,
What qualifies a system to be in a domain?
How do we say that a system is in X domain?
Does its host name being x.y.com put it in y domain? or
Does the system having a entry in the DNS for a domain put it in that
domain?
Can one system be in multiple domains?
If yes, how does it help / make a difference?
A FQDN is supposed to be a concatenation of hostname and domain.
Say I have a system with IP 10.0.0.1.
hostname command shows
*server.myowndomain.net*
In My DNS I have an entry (my DNS is for domain serverpool.net)
*10.0.0.1 IN A dhcpserver*
now what is my FQDN?
Further my system is going to be referred to by other systems by what ever
name is in the DNS. Then what is the user of hostname mentioned locally.
Then there is NIS domain etc!!! All this confuses me. Someone please
clarify.
Regards,
Ashish
