|
|
>Whilst you can quite happily use the domain name servers located at your
|
|
ISP, you can also set up a local caching only (secondary) name server
|
|
that is brought up by the ip-up script. The advantage of running a local
|
|
(caching only) name server is that it will save you time (and bandwidth)
|
|
if you frequently contact the same sites during a long on-line session.</P
|
|
><P
|
|
>DNS configuration for a caching only nameserver (that uses a
|
|
"forwarders' line in the named.boot file pointing at your ISPs DNS) is
|
|
relatively simple. The O'Reilly book (DNS and Bind) explains all you
|
|
want to know about this.</P
|
|
><P
|
|
>There is also a DNS-HOWTO available.</P
|
|
><P
|
|
>If you are running a small LAN that can access the Internet through you
|
|
Linux PC (using IP Masquerade for example), it is probably a good idea
|
|
to run a local name server (with a forwarders directive) whilst the link
|
|
is up as this will minimise the bandwidth and delays associated with
|
|
name resolution.</P
|
|
><P
|
|
>One point of Nettiquette: ask permission from your ISP before you start
|
|
using a secondary, caching only name server in your ISP's domain.
|
|
Properly configured, your DNS will not cause any problems to your ISP at
|
|
all, but if you get things wrong, it can cause problems.</P
