Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers
"DNS is is the Domain Name System. DNS converts machine names to
the IP addresses that all machines on the net have. Name serving on
Unix is commonly done by a program called named. This is a part of
the ``BIND'' package which is coordinated by Paul Vixie for The
Internet Software Consortium."
"PDNSD is a caching DNS proxy server. Unlike BIND, it saves the
RAM cache to a file and the same is read up by PDNSD for the next
Dial-Up session. BIND when acting as a cacheing nameserver on your
local Dial-Up machine stores/caches the name to number translation
data in your RAM. This is not written back to the hard-disk upon
disconnection 'coz it is not intended for a user/site who/which is
not always connected to the Net."
"PDNSD can be configured to speed up Net Surfing on a Dial-Up
connection. Since DNS resolution is referenced from the cached
file, time is not wasted on the name to number lookup. This in turn
speeds up the name to number translation, which actually
accelerates your surfing."
