SonicOS 5.8.1 Administrator Guide
• 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.
Address Object Groups
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.
