The need for domain names

As applications grow to span multiple hosts, then networks, and

finally internets, these applications must also span multiple

administrative boundaries and related methods of operation

(protocols, data formats, etc). The number of resources (for

example mailboxes), the number of locations for resources, and the

diversity of such an environment cause formidable problems when we

wish to create consistent methods for referencing particular

resources that are similar but scattered throughout the


The ARPA Internet illustrates the size-related problems; it is a

large system and is likely to grow much larger. The need to have

a mapping between host names (e.g., USC-ISIF) and ARPA Internet

addresses (e.g., is beginning to stress the existing

mechanisms. Currently hosts in the ARPA Internet are registered

with the Network Information Center (NIC) and listed in a global

table (available as the file HOSTS.TXT on the SRI-NIC

host) [1]. The size of this table, and especially the frequency

of updates to the table are near the limit of manageability. What

is needed is a distributed database that performs the same

function, and hence avoids th...
