Hello,
I have a lot of subdomains to create. like aaa.mydomain.com aab.mydomain.com. It is too much work to create them all, does bind support a kind of "global" that alows you to type anything you want as subdomain like aaa123855sss.mydomain.com.

Thanks

If you mean you want [anythingatall].mydomain.com to point to the same place, you can use wildcards in the host field of a record, such as:

* IN CNAME mydomain.com.

Note however that this wildcard will take precedence and any other host entries for mydomain.com will not necessarily point to where you want them, for example:

...
@ IN A 192.168.1.100
test IN A 192.168.1.101
* IN CNAME mydomain.com

test.mydomain.com and blah.mydomain.com will resolve to 192.168.1.100.

This setup plus a bit of cgi-scripting is how websites like http://jnsc.isgay.com work. Just out of curiosity, why do you need to create so many subdomains (if in fact, the wildcard thing is what you wanted).

Thanks, I'll try your solution.

I want do make a search engine which uses the subdomain as query. like if someone type hapy.mydomain.com the search engine will say are you looking for happy.mydomain.com.
