I want to optimize the call to remote dns server to resolve domain names each time needed. What i want to do is that if the hostname is requested for the first time than call the remote dns (for example 8.8.8.8) to resolve it, once called then recorded for later use in such way when next time the seem domain name is requested for resolve than the cached ip is grabbed without need to call remote dns to maximize speed to optimize network traffic.
This is how BIND normally works.
It doesn't seem to use the cache, here is the call of dig mail.com : ; <<>> DiG 9.8.1-P1 <<>> mail.com

How did you come to the conclusion that caching does not work? -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
