| 11 | .SH DESCRIPTION | |
| 12 | The | |
| 13 | .I hosts | |
| 14 | file contains information regarding | |
| 15 | the known hosts on the DARPA Internet. | |
| 16 | For each host a single line should be present | |
| 17 | with the following information: | |
| 18 | .HP 10 | |
| 19 | official host name | |
| 20 | .br | |
| 21 | .ns | |
| 22 | .HP 10 | |
| 23 | Internet address | |
| 24 | .br | |
| 25 | .ns | |
| 26 | .HP 10 | |
| 27 | aliases | |
| 28 | .PP | |
| 29 | Items are separated by any number of blanks and/or | |
| 30 | tab characters. A ``#'' indicates the beginning of | |
| 31 | a comment; characters up to the end of the line are | |
| 32 | not interpreted by routines which search the file. | |
| 33 | This file is normally created from the official host | |
| 34 | data base maintained at the Network Information Control | |
| 35 | Center (NIC), though local changes may be required | |
| 36 | to bring it up to date regarding unofficial aliases | |
| 37 | and/or unknown hosts. | |
| 38 | .PP | |
| 39 | Network addresses are specified in the conventional | |
| 40 | ``.'' notation using the \fIinet_addr\fP() routine | |
| 41 | from the Internet address manipulation library, | |
| 42 | .IR inet (3N). | |
| 43 | Host names may contain any printable | |
| 44 | character other than a field delimiter, newline, | |
| 45 | or comment character. | |

| 47 | When using the name server this file is used as a backup for when | |
| 48 | .IR named (8) | |
| 49 | is not running. | |
| 50 | For the name server it is suggested that only a few addresses | |
| 51 | be included in this file. | |
| 52 | These include address for the local interfaces that | |
| 53 | .IR ifconfig (8C) | |
| 54 | needs at boot time and a few machines on the local network. | |
