Hi all, I am trying to trace a recursive outbound query. My workstation is configured to point to the forwarder/resolver 192.168.0.2, which is a dedicated forwarder that is configured to forward all DNS queries to the ISP's DNS resolver. Sometimes I get name resolution failures, and I want to know if it is the ISP's DNS resolver is forwarding recursive queries to yet another server... when using 'dig example.com +trace', it only shows the recursive lookup starting at the root domain, instead of showing from my 192.168.0.2 -> ISP -> ? -> root name servers.
Is there any way to discover all the forwarders/resolvers along the way before my query hits one of the root name servers? Or is that an impossible feat unless I have administrative access to each of the resolvers/forwarders to look at its configuration? Thanks in advance. -Josh
