I would like to know how to configure bind9 to resolve all DNS requests given to it iteratively starting with a root server.
My goal with this is to set up bind9 as a dns resolver in my local network, however my preferences are rather specific in that I do not wish to trust any external recursive resolver, be it Google’s 188.8.131.52 or any of the sort. I would like my recursive resolver to resolve a A query for let’s say test.example.com as follows:
1. ask a root server for the NS entry for .com
2. ask the server given by 1. for the NS entry for example.com
3. ask the server given by 2. for the NS entry for test.example.com
4. ask the server given by 3. for the A entry for test.example.com
(I am not entirely sure but from what I understand this scheme is called iterative resolving?)
Ideally I want the intermediary servers to know as little as possible on what domain I am actually querying and preferably as many requests as possible should be made using dnsseq. Caching of all these entries is desired, but not required.
Sidenote: My network does not support ipv6.
I know that this kind of resolver is probably going to be slower than 184.108.40.206, but for me this loss in performance is negligible /acceptable.
I did not find instructions on how to configure bind9 to perform requests exactly this way.
Is it even possible to configure bind9 this way or do i have to write my own resolver from scratch?
If it is possible could someone post a snipped of
that makes this possible or points me in the right direction.
I am also open to any alternatives that will serve my purpose.
In case it matters I am using Ubuntu 16.04 LTS (Armbian Linux)
