+ | hosts - The static table lookup for host names | ||

+ | SYNOPSIS | ||
+ | / | ||
+ | |||
+ | DESCRIPTION | ||
+ | | ||
+ | file is a simple text file that associates IP addresses with hostnames, | ||
+ | one line per IP address. | ||
+ | with the following information: | ||
+ | |||
+ | IP_address canonical_hostname [aliases...] | ||

+ | The Berkeley Internet Name Domain (BIND) Server implements the Internet | ||
+ | | ||
+ | file or host name lookup, and frees a host from relying | ||
+ | being up to date and complete. | ||
+ | |||
+ | | ||
+ | DNS, it is still widely used for: | ||
+ | |||
+ | | ||
+ | Most systems have a small host table containing | ||
+ | address | ||
+ | This is useful when DNS is not running, for example during | ||
+ | tem bootup. | ||
+ | |||
+ | | ||
+ | database. | ||
+ | still use the host table with an entry for all local hosts as a | ||
+ | backup. | ||
+ | |||
+ | | ||
+ | Very small sites that are isolated from the network use the host | ||
+ | table instead of DNS. If the local information rarely changes, | ||
+ | and the network is not connected to the Internet, | ||
+ | little advantage. | ||
