There have been DNS Cache on the post, so I learned a lot of skills, the aggregate.

Q: How can I view the BIND DNS Server Cache: 

A: In bind 9, you can use rndc-dumpdb order to view the DNS Cache, of course, you have to configure the rndc good. This command will be in / var / named (in this directory is specified in the named.conf file) generated in the directory named_dump.db documents.

In bind 8, might try to kill-INT named_pid.

Q: DNS Cache of time how to set up:

A: In bind 9, the use of TTL to set the parameters of the default DNS cache, but you have to remember this is the analysis of the domain name in other people's DNS cache in time.

Q: How do I clear my client DNS Cache:

A: Under the Unix, DNS client is only a few routines, forward and accept responsibility for the function, not the cache.

In Windows 2000 & XP under: ipconfig / flushdns can clear the cache;

ipconfig / displaydns can display the dns cache.

dns cache under the windows by dns client background process control, you can control panel -> services will be closed, such windows would not be carried out dns cache, each will have a direct enquiries dns server.   Hong Kong Network Service company Limited
