IP/Mask | There are three ways to use this database. Choices |
| are Single IP, IP Range, or Subnet Mask. Your |
| selection depends on whether you want to specify |
| one IP address for an entire group, a range of IP |
| addresses for a group, or a range of subnet masks |
| for a group. |
|
|
IP Entry Name | Name of your choosing. Purpose is to identify the IP |
| group you want to set up. Maximum field length=19 |
| characters. |
|
|
IP addr.1 | IP address that you want to assign to a group. |
| If you selected Single IP, enter that IP address here. |
| If you selected the IP Range option because you |
| want to designate a range of addresses, enter the |
| beginning of the range here and enter the ending |
| range in the IP addr.2 field. |
| If you selected the Subnet Mask option, enter the |
| desired IP address here and enter the subnet mask |
| in the IP addr.2 field. All addresses falling within that |
| subnet will be included in the group you set up. |
|
|
IP addr.2 | If you are using the Single IP option, this field is not |
| applicable. |
| If you are using the IP Range option, enter the end |
| of the IP address range here. Note: IP addr.1 has to |
| contain the beginning of the range. |
| If you are using the Subnet Mask option, enter the |
| subnet mask here. The subnet mask divides IP |
| addresses into groups. In the IP addr.1 field, you |
| must enter an IP address of the group that you want |
| in the database. All IP addresses within the same |
| group as the address in the IP addr.1 field will be |
| affected. |
| For example, if you enter the IP address 192.168.0.1 |
| in the ip addr.1 field and the subnet mask |
| 255.255.255.0 in the ip addr.2 field, the group will |
| include the addresses 192.168.0.1 to 192.168.0.255 |
| (for a total of 255 addresses). If you enter the IP |
| address 192.168.0.1 in the ip addr.1 field, and the |
| subnet mask 255.255.255.240 in the ip addr.2 field, |
| the group will include the addresses 192.168.0.1 to |
| 192.168.0.15 (a total of 15 addresses). |
