RE: Catch ALL Setup

I tried messing around with some zone/hint files in an isolated setup, but without any success. What I am trying to achieve is the following: No matter which host/name is looked up, the DNS should spit out the same IP address. The intention is to bring the users to a specific webserver/webpage, not matter what web page the intend to surf to, for the easiness of setting up their connection. The basic idea is, unauthenticated clients will be put in an isolated network, users then pop up their web browser, will land on a specific webpage with instructions on which steps they need to take, to get proper access. I tried to create a * zone, which seems to be ignored by bind, or rather bind doesn't like the contents of the zone file. I'd appreciate any pointer to some information, how I can tweak bind to do such a thing. With best regards -Sven Sven - Use the same/normal domain.com zone file, but make an A record like this: *.wildcard.com. IN A 192.149.109.1 (replace above with your stuff, then xxx.wildcard.com should work for any request).

A resolver looking for 'test', hoping to find it as 'test.another.com' would query the name server for test.example.com first and get back 'test.example.com IN A 1.2.3.4.'. regards, Stacey In message 499b8e5a.5010...@whgl.uni-frankfurt.de, Sven Eschenberg writes: Dear list, I tried googling about a Catch-All setup for a DNS, with little success.

You also need to add additional address records which you are missing for ie and ucd.ie. The OP said that *everything* had to resolve to the one address. Everything includes the nameserver. The only thing that doesn't resolve is the root and I think one can get by without that resolving to a address.
