IP addresses are fundamental to the operation of the Internet.
They not only uniquely identify Internet nodes but also allow IP
routers to forward packets to their destinations.
IP addresses, being 32 bit numbers, are ideally suited for
computers but are far from usable to humans.
Therefore, the Domain Name System (DNS) was designed: a
distributed database, held by a hierarchical system of servers, that
is used by TCP/IP applications to map between hostnames and IP
addresses.
This chapter describes AST570' DNS abilities.
