I am having some trouble understanding the operation and configuration of DNS caching on a CE.
Does the listener command intercept the CE's DNS requests that would normally go to the nameserver configured with the "ip name-server" command(s) and send them to the name or address used in the listener command?
What does this mean: " The DNS server must know the DNS name of the host on which it is being enabled and map it to an IP address within its own cache."? I can't tell if the DNS server referenced is the CE.
Also, is it more common to limit the cache size on the smaller end of the scale or the upper end?
Thanks.
