• It increases understanding of the configuration by using meaningful symbolic names.
• Using address object names instead of entering numerical addresses reduces errors.
• By defining an IP address object just once in the address book, changing the definition
automatically also changes all references to it.
3.1.2. IP Addresses
IP Address objects are used to define symbolic names for various types of IP addresses.
Depending on how the address is specified, an IP Address object can represent either a single IP
address (a specific host), a network or a range of IP addresses and even a DNS name.
In addition, IP Address objects can be used for specifying the credentials used in user
authentication. For more information about this topic, see Chapter 8, User Authentication.
The following list presents the various types of addresses an IP Address object can hold, along
with what format that is used to represent that specific type:
Host A single host is represented simply by its IP address.
For example, 192.168.0.14.
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 IPv4 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 Address
This example adds the IPv4 host www_srv1 with IP address 192.168.10.16 to the address book:
Command-Line Interface
Device:/> add Address IP4Address www_srv1 Address=192.168.10.16
InControl
Follow the same steps used for the Web Interface below.
Web Interface
1. Go to: Objects > Address Book > Add > IP4 Address
2. Specify a suitable name for the IP host, in this case wwww_srv1
