I’m trying to write some code with Ruby. I need to write a DNS resolver.
I saw a resolv.rb but there is simple example that I can take.
Specifically, I need:
- Create object r (that resolvs my dns): something like r =
- Put hostname and ip in this object: something like r.add(hostname, ip)
- Consult if this object knows anything about a specific hostname:
something like r.query(hostname) --> ip
and consult if this object knows anything about a specific ip:
something like r.query(ip) --> hostname
- Specify what it has to do if it does not know nothing about a concrete
hostname or ip:
r.parentresolver(none) --> if r does not know ip of one hostname,
then there is no procedure for determining it
r.parentresolver(ip) --> the parent DNS for resolv unknown
I know that all of that can do with resolv.rb but I don’t know how.
Can you put me an example of how do it?
Thank you very much,
