Thanks for the replies. It seems things have stabilized for now and
I haven't seen the problem for two days (I haven't done anything
yet to my system).

What I have at present is... - nothing in System Preferences ->
Network -> TCPIP -> DNS Servers - my DSL router (10.0.0.2) in
/etc/resolv.conf - two DNS server addresses in my DSL router's 'DNS
server field'

this setup in my G4 desktop and G4 powerbook. I wanted it this way
so I would have the DNS addresses only in one place.

I take it that as I have it it's the DLS router's task to get the
DNS translation done. If I put the DNS addr. in my System
Preferences -> Network -> TCPIP -> DNS Servers, it will be my G4
that will do the translation. Am I correct?

Thanks again.

Your Mac ALWAYS perform the translations. /etc/resolv.conf is where
your Mac looks for DNS servers. /etc/resolv.conf is dynamic and will
change depending on what you have in your Network prefs and/or what
your DHCP server provides to the Mac.

Seems to me that the DNS translation is performed by the DNS server not
the client. There'd be no need for DNS servers otherwise. I am not
sure why the OP is looking at /etc/resolv.conf as that's completely
unnecessary in OS X. The System Preferences > Network > TCP/IP prefpane
tells you everything you need to know to configure.

The OP should enter the DNS server IP addresses into the appropriate
field and click "Apply Now." That ought to solve his problems. If not
then there are other issues at work and he should contact his ISP to
troubleshoot his connection.

If you are using DHCP, then it is the DHCP server's responsibility to
provide the DNS addresses. If you have a home Cable/DSL Router, then
it generally gets its DNS addresses from the ISP's DHCP server.

It depends on how things are set up. This is true if the DSL router is
in "bridge" mode and is basically transparent between the customer's
computer and the ISP's DHCP server. But if the DSL router is the DHCP
server for computers on the LAN and the router uses PPP to connect to
the ISP, then this is not true. The latter is the case with my ISP, for
example, and thus I need to enter all the server information into the
TCP/IP panel of System Preferences > Network.
