With DeleteOnRelease set to 0, the entry only gets an expired lease timestamp and can therefore be reactivated at a later time. Even if the old IP address is available, it would most likely not being chosen. The effect is that when the same client comes back after some time and asks for an IP address, no information about it’s previous IP address is available. The default behavior is to automatically delete the entry in the database. It defines whether a client entry in the databse is deleted upon DHCPRELEASE, or not. The DeleteOnRelease setting is new in V1.9. Please keep in mind that this will work only, when the client section includes the Index=n entry which is only the case after the client has been acquiring a new lease. In that situation and when DeleteClientsFromWrongIndex is 1, then DHCP server will delete the client entry and create a new one. If the same client tries to acquire a new IP address but from a different IPBIND_k interface then the software will recognize that n != k meaning the client section is created from a different IPBIND. In that case, the path is interpreted relative to the INI file.Īll newly created clients will get an entry in the client section Index=n where n is the number of the IPBIND_n. The file name can be specified with relative paths since V2.7. If no Database setting is defined, then the DHCP server assumes that the database is part of the dhcpsrv.ini file. New in V1.9.2: If no or section is found in the Database.ini file, then the dhcpsrv.ini config file is used for that instead. This allows a clean distinction between real settings and configuration for the DHCP server and the IP assignment database in which the client configurations are managed. All the rest, or client section goes into the Database.ini file. The Database setting allows to split the dhcpsrv.ini file into two parts. What makes a client a “known client” is an existing entry in the INI file such as: IgnoreUnknownClients only controls how the DHCP Server behaves when no IP address is assigned (declining request or keep quiet). Note: Important difference to IgnoreUnknownClients. If ConfigureUnknownClients is set to 0, then a client is assigned an IP address only if the client is already specified in the INI file. Since this is the default, there is no change to previous versions. Setting this to 1 tells the DHCP server to automatically configure unknown clients. This is not recommended in general usage but might be useful in special cases.ĬonfigureUnknownClients is available since V1.7. Setting ClearClientsOnStartup=1 basically removes all clients from the INI file every time the DHCP Server is started. Specify an empty BalloonTimeFormat=, in case no timestamp shall be shown in the balloon message. Time-zone name or abbreviation no characters if time zone is unknown Year without century, as decimal number (00 – 99) Week of year as decimal number, with Monday as first day of week (00 – 53) Weekday as decimal number (0 – 6 Sunday is 0) Week of year as decimal number, with Sunday as first day of week (00 – 53) The format supports the following (strftime style) sepcifications: %aĭate and time representation appropriate for localeĭay of year as decimal number (001 – 366)Ĭurrent locale’s A.M./P.M. Specifies the time and date format used in balloon messages. The default behavior (AssociateBindsToPools=0) is to view all IPPOOL_x as one big pool of IP addresses which can be assigned to any client regardless of the subnet IPBIND_x. ![]() Clients on subnet IPBIND_x get IP addresses assigned only from the pool defined by IPPOOL_x. ![]() The two entries with the same number “x” belong together. If the DHCP Server is configured to use more than one NIC with a separate subnet each (see Example 3 in the overview) then this entry associates the IPPOOL_x with the IPBIND_x. If the server should not take the standard values from Windows, then set AddStandardEntries=0.Īssociate the IP pools with the respective IP binds. This is convenient, because it makes it unneccessary to repeat all the DNS_x, WINS_x and ROUTER_x settings that were already made in Windows IP configuration. The default behaviour (AddStandardEntries=1) is to automatically add the standard values from the Windows configuration to the reply message. It allows to control the behaviour of the DHCP Server with respect to DNS_x, WINS_x and ROUTER_x entries in the replies from the server to the client. AddStandardEntries is a new setting in V2.3.4.
