Hello,
I need to setup a local named configuration so that ANY request will be

to a specific single IP only.
I mean any kind of DNS resolutin request
www.luth.se
www.isc.org
www.anything.tld
should be resolved in 172.16.30.30 for example
zone . {
type master;
file zone.root;
};
zone.root:
@ SOA ...
NS localhost
localhost A 127.0.0.1
* A 172.16.30.30
NOTE: this does exactly what you asked. And may have unexpected
consequences [as in, be careful what you ask for; you may get it]. For
instance, this had better be the name server, as well! NO OTHER IP
ADDRESS IN THE ENTIRE WORLD will be resolved.
Unless you add domains on this same name server.
Correct .. but as you say you just add domains on the same name server.
Simple make the NS the localhost and assign localhost the A record of
127.0.0.1. Or lets say the name server is at 172.16.30.31 then you can do as
follows
NS any.domain.name
any.domain.name A 172.16.30.31
* A 172.16.30.30
That will work too.

Oh, I see why - it thinks that the IP address is a domain NAME! You MUST have a name to the right of your NS record. But in this case, you have the host name 172 in the subdomain 16.30.30. Normally, to make this work, you must add 172.16.30.30. IN A172.16.30.30 and have a separate zone for the domain 16.30.30. [which is QUITE DIFFERENT from the domain 30.30.16.in-addr.arpa.]. If you don't understand this, think about it for a while - and about the fact that what is to the right of the NS record is NEVER interpreted as an IP address, it is ALWAYS interpreted as a name. Thank you for the amusing anecdote. ;-) $TTL86400 $ORIGIN . @ 1D IN SOA @ root ( 42 ; serial (d. adams) 3H ; refresh 15M ; retry 1W ; expiry 1D ); minimum 1D IN NS172.16.30.30 * IN A172.16.30.30 -- /*\ ** ** Joe Yao j...@tux.org - Joseph S.

You know, when I wrote this I was thinking of the recommended separate resolving name server from authoritative name server. But in the case our friend from Italy was describing, usually they are the same. If the resolving name server to which all the workstations or kiosks are pointing has a different IP address from the uiniversal IP address, it really doesn't matter! ;-) -- /*\ ** ** Joe Yao j...@tux.org - Joseph S.

Re: how to setup a local root nameserver?
Thats the baptista vortex. I've used it to clean up root servers of traffic.
Where every name resolves to the same IP address. I don't know if it still
works under bind. You can try.
You simply setup a root zone file with a wildcard pointing to the A record.
Or you can build a server to do that.

I need this because I need to redirect users to a local web portal
authentication page and I need
to do it using DNS.
is there any kind of named configuration which can allow me to achieve this
result ?
I tryed hard but without any success
for example I tryed this:
in named.conf:
zone . IN {
type master;
file named.root;
};
then in named.root:
$TTL86400
$ORIGIN .
@ 1D IN SOA @ root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ); minimum
1D IN NS@
1D IN A 172.16.30.30
but it works only for .
and not recursively for anydomain issued in the request.
thank you
Rick
