Which file is this? If you mean the filename for secondary service, the
server will create this file as needed.

There's a difference between web servers and DNS servers. The IP addresses
shown in the example are the authoritative (primary) DNS servers involved
in the ft/lb operation for that domain. You only need one.

You do need multiple *web* servers to make ft/lb meaningful. However, this
is configured in the load balancing record.

>How do I name my secondary?

However you want. I noticed, for example, that the two name server for your
reverse zone are:
ns.inreach.com.
dogbert.inreach.com.

>Quick DNS pro doesn't do admin via tcp/ip does it?

Not at this time.

Change it to the name of your primary name server, which is currently
ns.valueport.com. Of course, I've already counseled you to change that to
ns1.valueport.com.

Just on the secondary.

The secondary DNS server will continue to serve out your DNS data. 3 hours
after its last check, it will again try to check your primary to see if
there's a more recent version of your domain. If the primary is down, it
will retry 2 hours later. If, after 7 days, it still can't contact your
primary, it will stop serving out valueport.com. (I took these values of 3
hours, 2 hours, and 7 days from your domain information; they are
completely configurable.)

>but there aren't. I used the domain assistant to set up all my stuff, and

You don't have authority for your reverse (PTR) records. If you want that,
you'll need to talk to your service provider.

>What are all these two arpa records?

You mean "in-addr.arpa"? That's the format of a reverse zone name. For
instance, the PTR record for 209.209.9.59 might look like this:
59.9.209.209.in-addr.arpa. PTR valueport.com.

There should be no more than one PTR record for any given IP address.
Reverse records go in their own zone file.

>examples of actual records would be great.

Is the above sufficient?
