When I do simple nslookup it does not generate any query for IPV6 (AAAA). But sometimes I see DNS query for both A and AAAA are generated. What decides this? The reason I do not want AAAA query is in most of the cases AAAA records are absent. Hence, if one DNS server fails, the clients keeps... (1 Reply)

My question is how can I make... (2 Replies)

DNSTRACER(8) General Commands Manual DNSTRACER(8)NAME
dnstracer - trace a chain of DNS servers to the source
dnstracer [options] name
dnstracer determines where a given Domain Name Server (DNS) gets its information from, and follows the chain of DNS servers back to the
servers which know the data.
-c Disable local caching.
-C Enable negative caching.
-o Enable overview of received answers at the end.
Change the query-class, default is A. You can either specify a number of the type (if you're brave) or one of the following
strings: a, aaaa, a6, soa, cname, hinfo, mx, ns, txt and ptr.
Number of retries for DNS requests, default 3.
DNS server to use for the initial request, default is acquired from the system. If a dot is specified (.), A.ROOT-SERVERS.NET will
-v Be verbose on what sent or received.
-4 Use only IPv4 servers, don't query IPv6 servers (only available when IPv6 support hasn't been disabled)
Use this as source-address for the outgoing packets.
HOW IT WORKS
It sends the specified name-server a non-recursive request for the name.
Non-recursive means: if the name-server knows it, it will return the data requested. If the name-server doesn't know it, it will return
pointers to name-servers that are authoritive for the domain part in the name or it will return the addresses of the root name-servers.
If the name server does returns an authoritative answer for the name, the next server is queried. If it returns an non-authoritative answer
for the name, the name servers in the authority records will be queried.
The program stops if all name-servers are queried.
Make sure the server you're querying doesn't do forwarding towards other servers, as dnstracer is not able to detect this for you.
It detects so called lame servers, which are name-servers which has been told to have information about a certain domain, but don't have
Search for the A record of www.mavetju.org on your local nameserver:
Search for the MX record of mavetju.org on the root-nameservers:

Search for the PTR record (hostname) of 18.104.22.168:
dnstracer "-q" ptr 22.214.171.124.in-addr.arpa
And for IPv6 addresses:
