DNS/DHCP Management Console
IP addresses are a system of logical addresses used to identify hosts on a network. IP address property pages are used to manually configure individual IP addresses. To access IP address property pages, Addressing, Usage, and Other DHCP Options, double-click a Subnet object from the DHCP directory window, then select an IP Address object from the extended schema. IP Address objects are displayed in different colors depending on their assignment type.
Addressing: Use this tab to specify Dynamic, Exclusion, or Manual IP address assignment types.
Note: IP Address objects with assignment type as Unauthorized appear in red. You cannot create IP address of this assignment type using the DNS/DHCP management console. Unauthorized IP Address is an IP address, which is used by a client machine without the knowledge of DHCP server, that is, the corresponding IP Address object is not present in the IP Address database. When you select the Ping Enabled option of DHCP Server, it pings to an IP Address to check whether it is used by a client before assigning it to another client. If an IP address is used without its knowledge, the DHCP server creates an IP Address object in the database with the assignment type as Unauthorized.
Usage: Use this tab to assign permanent or timed lease expiration options to a manually assigned address.
Other DHCP Options: Use this tab to add, delete, update, or specify default DHCP options for a manually assigned address type. Default is used to display DHCP options inherited from global preferences and the Subnet object that the address object is under. For a list of DHCP options and parameter definitions, refer to the Novell® DNS/DHCP Services Administration Guide.
