Advanced Research Projects Agency (ARPA). An agency of the United States
Department of Defense, ARPA underwrote the development of the Internet beginning
in 1969. Known as ARPANET, it was designed so that, in case of war and the loss of
any group of sites, remaining sites would still be able to communicate along alternate
routes. No site would be critical to the operation of the network. Eventually, ARPANET
was divided into Milnet, which connected military sites, and a new ARPANET that
connected other sites, mainly universities. A new communication protocol was
developed, TCP/IP, so that all sites on either of the networks could communicate.

Berkeley Internet Name Domain (BIND). An implementation of the DNS protocols that
provides an openly redistributable reference implementation of the major components
of the DNS, including the named process, the DNS resolver library, and tools for
verifying the proper operation of the DNS server. The BIND DNS Server is used on the
vast majority of name-serving machines on the Internet, providing a robust and stable
architecture on top of which an organization's naming architecture can be built.
BIND. See Berkeley Internet Name Domain (BIND).
DNS. See Domain Name System (DNS).
Domain Name System (DNS). A system that defines a hierarchical, yet distributed,
database of information about hosts on a network. A domain name is a meaningful and
easy-to-remember “handle” for an Internet address. The network administrator
configures the DNS with a list of hostnames and Internet protocol (IP) addresses,
allowing users of workstations that are configured to query the DNS to specify remote
systems by hostnames rather than by IP addresses. DNS domains should not be
confused with Windows NT networking domains.
glue records. When an Address record (A record) is used to provide the IP address of a
name server that does not belong to the current domain, the
A record is also called a
glue record.
Guardian. An environment available for interactive or programmatic use with the HP
NonStop™ operating system. Processes that run in the Guardian environment usually
use the Guardian system procedure calls as their application program interface.
Interactive users of the Guardian environment usually use the HP Tandem Advanced
Command Language (TACL) or another HP product’s command interpreter. Contrast
with Open System Services (OSS)
.
Incremental Zone Transfer (IXFR). A protocol enhancement to full zone transfer
mechanism (AXFR) that transfers only the changed portion of a zone instead of
transfering the entire zone file.
