MAC Address – MAC Address Objects allow for the identification of a host by its hardware 
address or MAC (Media Access Control) address. MAC Addresses are uniquely assigned 
to every piece of wired or wireless networking device by their hardware manufacturers, and 
are intended to be immutable. MAC addresses are 48 bit values that are expressed in 6 
byte hex-notation. For example “My Access Point” with a MAC address of 
“00:06:01:AB:02:CD”. MAC Addresses are resolved to an IP address by referring to the 
ARP cache on the security appliance MAC Address objects are used by various 
components of Wireless configurations throughout SonicOS.

FQDN Address – FQDN address objects allow for the identification of a host by its Fully 
Qualified Domain Names (FQDN), such as 'www.sonicwall.com'. FQDNs are be resolved 
to their IP address (or IP addresses) using the DNS server configured on the security 
appliance. Wildcard entries are supported through the gleaning of responses to queries 
sent to the sanctioned DNS servers.

SonicOS Enhanced has the ability to group Address Objects into Address Object Groups. 
Groups of Address Objects can be defined to introduce further referential efficiencies. Groups 
can comprise any combination of Host, Range, or Network Address Objects. MAC Address 
Objects should be grouped separately, although they can safely be added to Groups of IP-
based Address Objects, where they will be ignored when their reference is contextually 
irrelevant (e.g. in a NAT Policy). For example “My Public Group” can contain Host Address 
Object “My Web Server” and Range Address Object “My Public Servers”, effectively 
representing IP Addresses 67.115.118.66 to 67.115.118.90 and IP Address 67.115.118.110.

The Network > Address Objects page allows you to create and manage your Address 
Objects.

You can view Address Objects in the following ways using the View Style menu:
