But is it possible to use wildards without own IP? How to setup the dns?[/quote:f29073249b]
Wildcard A, CNAME and MX records are possible

You have to add like this record in your zone file.

[b:f29073249b]*.domain.com. IN A 10.20.30.40[/b:f29073249b]

But if you have i.e this record too
www IN A 10.20.30.41

Then any attempt to lookup hosts for that domain will resolve this way:

corporate.domain.com
staff.domain.com
support.domain.com
…
All of them will resolve to -& 10.20.30.40

Except for www which you have another A record for it:

www.domain.com -& 10.20.30.41

However it is not recommended to set up wildcard DNS (please read my last post in this thread)
