TCP/IP Host Tables
Host tables are a method for mapping host names to IP addresses. This is done by
using a hosts file for name-to-address resolution. Because the host table lacks the
structure to list names in any hierarchical order, names assigned to hosts must be
unique. In the topics that follow, you will find discussions about the overall
management of TCP/IP host tables. Instructions for merging host tables and
managing a host table from a central site are included.
Successful TCP/IP host table maintenance also includes periodically evaluating
whether or not to use a DNS server to manage your network. The DNS server is
often the preferred alternative to host tables for the purpose of managing IP
addresses and host names, particularly in large network environments. However,
even some small organizations that access the Internet require a DNS server to
meet their name-service needs.
