namepool - DHCP server database DESCRIPTION
The namepool database provides joind with names that are available for dynamic assignment to clients of the DHCP protocol. For each DHCP server and domain name (NIS or DNS), the database contains a collection of names available for allocation to DHCP clients within those domains. One name plays a distinguished role - it is used as a prefix when the pool has been exhausted. Names are generated from the pre- fix by appending a number, 1,2.., and a trailing 'd'. The namepool file is read whenever joind starts. Names within the database must not be allocated to hosts which are not DHCP clients, and if the administration of a domain is shared between several DHCP servers, the name- pools that each has must be disjoint. Names may be added and removed from the namepool file. If a name is removed from the file it remains bound to the client to which it was allocated; if no such binding is in effect the name is excised from the server's pool the next time the server starts. Once a name is dynamically bound to a host it will never be reused even if that host subsequently acquires a new name, but there is no need to remove it from namepool. FORMAT Blank lines and lines beginning with a number sign (#) are ignored. A new entry must begin in column one and has one of the following for- mats: domain server domain server name_prefix The domain variable is the domain in which the names which follow are assigned. The server variable is the name or IP address of the server in charge of allocating these names to clients. The prefix variable is the prefix that will be used when the pool is exhausted. Succeeding lines contain one or more names for domains that are to be allocated by the server. Each of these succeeding lines must begin with at least one white space character. FILES
