Bind would refuse to load that zone since a wildcard can't have NS

As I've mentioned, "unbound" can do this. If the OP want's to stick with 
bind, but can tolerate it, he could do something like:


zone "abcd.com" {
  type forward;
  forward only;
  forwarders { 127.0.0.1 port 5300; };
};

...and then run a copy of unbound locally with unbound.conf:

port: 5300
local-data: "www.abcd.com 600 IN A "

...plus other required config of course.

RE: one record to be redirected to a specific IP

[hugo hugoo]

What I want to do is redirect a site to a specific IP using DNS (this kind of 
request comes from the Justice).

This specific IP can be an internal website with a warning message for example.

 

So I need to could redirect www.abcd.com for example to a specific IP 1.2.3.4 
for example.

This redirection must not have any impact on other ur'ls like toto.www.abcd.com 
or "anything else".www.abcd.com

 

 

I  am also wondering if this is a problem to impact "anything 
else".www.abcd.com, if this kind of URL exists.

 

Thanks in advance for your help in this DNS world new to me.

Your answer seems to indicate thate there is no way to only redirect 
www.abcd.com to IP 1.2.3.4
toto.www.abcd.com will either be redirected to the same IP (zone file with * A 
1.2.3.4) or answered with NX record (zonz file with 
www.abcd.com A 1.2.3.4)

So can we redirect only www.abcd.com without any impact on 
toto.www.abcd.com?



Not in bind. unbound can do this.

That's essentially correct.

It doesn't have to be the same IP, it could be a different one. You can
even specify some specific host names with certain IP addresses, with or
without a wild card for everything else. There are a lot of
possibilities, but until you tell us EXACTLY what it is you want to
accomplish, it's next to impossible to provide you useful help.

> So can we redirect only www.abcd.com without any
> impact on toto.www.abcd.com?

No. Once you create a zone www.abcd.com it will have an impact on
.www.abcd.com.

toto.www.abcd.com will either be redirected to the same IP (zone file with * A

So can we redirect only www.abcd.com without any impact on toto.www.abcd.com?

You need to create a zone for just that record.

In named.conf:
zone "www.abcd.com" {
type master;
file "/etc/namedb/master/www.abcd.com";
};

For the file line above replace the path to indicate where your actual
zone files are stored.

In the zone file, you would do this:
$TTL 3h
www.abcd.com. SOA localhost. nobody.localhost. 42 1d 12h 1w 10m
; Serial, Refresh, Retry, Expire, Neg. cache TTL

NS  localhost.
A   1.2.3.4


Hope this helps,

Doug
