In order to accomplish this, the company will set up two sets

To protect the <code class="filename">site1.internal</code> and <code class="filename">site2.internal</code> domains,
the internal name servers must be configured to disallow all queries
to these domains from any external hosts, including the bastion
hosts.
</p>
<p>
The external servers, which are on the bastion hosts, will
be configured to serve the "public" version of the <code class="filename">site1</code> and <code class="filename">site2.example.com</code> zones.
This could include things such as the host records for public servers
(<code class="filename">www.example.com</code> and <code class="filename">ftp.example.com</code>),
and mail exchange (MX) records (<code class="filename">a.mx.example.com</code> and <code class="filename">b.mx.example.com</code>).

</p>
<p>
In addition, the public <code class="filename">site1</code> and <code class="filename">site2.example.com</code> zones
should have special MX records that contain wildcard (`*') records
pointing to the bastion hosts. This is needed because external mail
servers do not have any other way of looking up how to deliver mail
to those internal hosts. With the wildcard records, the mail will
be delivered to the bastion host, which can then forward it on to
internal hosts.

Now that they accept mail on behalf of anything in the internal
network, the bastion hosts will need to know how to deliver mail
to internal hosts. In order for this to work properly, the resolvers
on
the bastion hosts will need to be configured to point to the internal
name servers for DNS resolution.

Although the "official" beginning of the Domain Name
System occurred in 1984 with the publication of RFC 920, the
core of the new system was described in 1983 in RFCs 882 and
883. From 1984 to 1987, the ARPAnet (the precursor to today's
Internet) became a testbed of experimentation for developing the
new naming/addressing scheme in a rapidly expanding,
operational network environment. New RFCs were written and
published in 1987 that modified the original documents to
incorporate improvements based on the working model. RFC 1034,
"Domain Names-Concepts and Facilities", and RFC 1035, "Domain
Names-Implementation and Specification" were published and
became the standards upon which all <acronym class="acronym">DNS</acronym> implementations are
built.

The first working domain name server, called "Jeeves", was
written in 1983-84 by Paul Mockapetris for operation on DEC
Tops-20
machines located at the University of Southern California's
Information
Sciences Institute (USC-ISI) and SRI International's Network
Information
Center (SRI-NIC). A <acronym class="acronym">DNS</acronym> server for
Unix machines, the Berkeley Internet
Name Domain (<acronym class="acronym">BIND</acronym>) package, was
written soon after by a group of
graduate students at the University of California at Berkeley
under
a grant from the US Defense Advanced Research Projects
Administration
(DARPA).

Versions of <acronym class="acronym">BIND</acronym> through
4.8.3 were maintained by the Computer
Systems Research Group (CSRG) at UC Berkeley. Douglas Terry, Mark
Painter, David Riggle and Songnian Zhou made up the initial <acronym class="acronym">BIND</acronym>
project team. After that, additional work on the software package
was done by Ralph Campbell. Kevin Dunlap, a Digital Equipment
Corporation
employee on loan to the CSRG, worked on <acronym class="acronym">BIND</acronym> for 2 years, from 1985
to 1987. Many other people also contributed to <acronym class="acronym">BIND</acronym> development
during that time: Doug Kingston, Craig Partridge, Smoot
Carl-Mitchell,
Mike Muuss, Jim Bloom and Mike Schwartz. <acronym class="acronym">BIND</acronym> maintenance was subsequently
handled by Mike Karels and Øivind Kure.
