IP Network
An IP Network is represented using Classless Inter Domain Routing (CIDR) form.
CIDR uses a forward slash and a digit (0-32) to denote the size of the network as a
postfix. This is also known as the netmask.
/24 corresponds to a class C net with 256 addresses (netmask 255.255.255.0), /27
corresponds to a 32 address net (netmask 255.255.255.224) and so on.
The numbers 0-32 correspond to the number of binary ones in the netmask. For
example: 192.168.0.0/24.
IP Range
A range of IP addresses is represented with the form a.b.c.d - e.f.g.h.
Note that ranges are not limited to netmask boundaries. They may include any
span of IP addresses. For example, 192.168.0.10-192.168.0.15 represents six hosts
in consecutive order.
Example 3.1. Adding an IP Host
This example adds the IP host www_srv1 with IP address 192.168.10.16 to the address book:
Command-Line Interface
gw-world:/> add Address IP4Address www_srv1 Address=192.168.10.16
Web Interface
1.
Go to Objects > Address Book > Add > IP address
2.
Specify a suitable name for the IP host, in this case wwww_srv1
3.
Enter 192.168.10.16 for the IP Address
4.
Click OK
Example 3.2. Adding an IP Network
This example adds an IP network named wwwsrvnet with address 192.168.10.0/24 to the address book:
Command-Line Interface
gw-world:/> add Address IP4Address wwwsrvnet Address=192.168.10.0/24
Web Interface
1.
Go to Objects > Address Book > Add > IP address
2.
Specify a suitable name for the IP network, for example wwwsrvnet
3.
Enter 192.168.10.0/24 as the IP Address
4.
Click OK
