Hi everybody,

We have a server with more than one A record:

aserver.domain.com 10.1.1.1
aserver.domain.com 10.1.1.2

I just want to know what happen when I look up at the name
aserver.domain.com? I suppose the DNS will "rotate"
between 10.1.1.1 and 10.1.1.2?

The second question is what happen if one of the addresses
failed? I suppose the DNS is not smart enough to select
the "correct" address?

Thanks
J.

Yes it will...Round Robin.

No, it's not smart enough.
Why have two records? Why not just use the one because it;s only one server?
I can see if you have two machines and you want to load balance between
them, we can use the Round Robin feature to divvy up client requests between
the two IPs, but not with one server.

Thanks
