Quote:Resolving Domains Internally And Externally With Bind9 And Caching Nameserver
Some times, we are required to resolve our internal domains on a local nameserver and external (Internet) domains from ISP's nameserver. There are different solutions to this problem, but in this howto, we are going to solve it through configuring a combination of caching-nameserver and BIND 9...
Theory Behind Caching-Namerserver and BIND 9:
Caching-Nameserver is a type of nameserver that will resolve a web addresses (domain names) from its next or master DNS, and will keep those entries in cache, after first time resolution it will resolve DNS queries locally, untill its TTL (Time To Live) is expired.
BIND 9 is used to resolve domain resolution queries from it own database, as it is SOA (Start Of Authority)....
