Correct.

Yes, as long as you never want to do similarly for the inside.

You might want to make your internal domain a sub-domain, though, like
    internal.tradersdata.com.

Then, you won't have a conflict if you ever have an external name, like,
say, "www" web server, and then later want to use that same name
internally.  Then, from the inside,  www.tradersdata.com gets the
external address, while www.internal.tradersdata.com gets the intranet
web server.

Subject: hosts resolve, but not domain



Setup: bind 4.9.7 on Linux

I have one public static IP, with a private class C masqueraded
behind a gateway. The provider does public dns (1) and I've set up
primary and secondary servers for the LAN only.  Everything works
fine, except my internal servers do not resolve tradersdata.com to
the external IP.  External servers resolve both tradersdata.com
and mail.tradersdata.com to that IP.  My internal servers handle
any internal node (and all resolver needs) correctly, but do not
resolve tradersdata.com.  It doesn't seem to hurt anything, but
doesn't seem right.

Thinking about this a little more... I was expecting my servers to
go outside to resolve this since nothing in my configuration points
to that IP, but I'm guessing they don't because they think they're
authoritative.  So can I simply add an A resource record for the
domain that points to the public IP?

(1) Everything works fine, but a ptr query of the public IP returns
the providers fqdn for that IP, not tradersdata.com.  Should that
matter to me?

Thanks for any help/pointers.
