Step 1:TheDNS Resolverservice running inDNS Clientcontacts the local DNS Server (Recursive DNS Server) with a Recursive DNS Query to resolve theFully Qualified Domain Name (FQDN), www.omnisecu.com. The Local DNS Server must now answer the Query with the IP Address corresponding to theFully Q...
If you are interactively logged on to the console of a server using say a browser, then the client side resolver will construct a recursive query to the DNS address in the first entry of the NIC properties, basically asking, "I don't care how you get the answer, I just want an ...
Aniterative name queryis one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is areferral(that ...
The method comprises the steps of: when a secondary telephone number mapping working group/domain name system (ENUM/DNS) server receives an iterative query request from a client, first inquiring the local data; if the query of the local data is failed, inquiring address information of a target...
I originally wrote this program to investigate the behavior of authoritative servers in the presence of query name minimization. Since then I've gradually developed it into a more full fledged iterative resolver. These days, I typically use this program to debug a variety of DNS problems. I ...
