The first two name server entries are OK. The third is not and may cause
you problems. The purpose of a name server is to translate host names to
IP addresses. It is sort of circular to supply a host name with needs to
bee looked as the address of the thing that is responsible for looking up
host names. See what I mean?

You can use dialin.ucsd.edu as a nameserver, but you need to name it using
its IP address. So:

[j:\tmp\0]nslookup dialin.ucsd.edu
Server: rns2.earthlink.net
Address: 207.217.77.82

Non-authoritative answer:
Name: dialin.ucsd.edu
Address: 137.110.0.26

which says:

nameserver 137.110.0.26

will work for now. Since nslookup does not list 137.110.0.26 as a name
server, ucsd might be planning to stop using it as a name server, so it
might stop working in the future.

The DNS can change for several reasons. The most common is load sharing.

It should not do this. You need to use iptrace to find out where Mozilla
is going astray. To use iptrace with Injoy, you need to tell Injoy to
export the trace data.

Perhaps. One can only guess until one sees some trace data.

Once you have trace data that clearly shows the problem, reporting is is
easier.

Merry ho ho,
