Domain Name
A Domain is a set of computers on a network that have been assigned a group name. If you have
chosen to set the IP address for the AXIS 9010 manually, you can specify the Domain Name to
which the AXIS 9010 belongs.
Gateway
A gateway is a network point that acts as an entrance to another network. If you choose to set
the IP address for the AXIS 9010 manually and wish to access the Internet, you must specify the
Default gateway.
IP Address
In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-bit
binary digit number that identifies each sender or receiver of information that is sent in a packet
across the Internet.
IP Masquerading
A firewall or router performs IP Masquerading if it changes the source IP address and port num-
ber on every packet that originates from one side of the client before forwarding that packet to
the other side. Returned packets are similarly translated, so that they return to the internal
machine which initiated a connection. IP Masquerading is a popular method for hiding a pro-
tected IP address space from the Internet. Internal users access services on the Internet as usual,
but Internet services only see connections that originate on the firewall or the router. IP Mas-
querading uses almost the same method for IP translation as NAT, except that masquerading also
uses the port number in the translation.
ISP
An ISP (Internet Service Provider) is a company that provides access to the Internet and other
related services.
Link key
A link key is partly based on the Bluetooth Passkey and is created and exchanged as authentica-
tion when establishing connection between
Bluetooth
devices.
MAC Address
On a local area network or other networks, the MAC (Media Access Control) address is your com-
puter's unique hardware number, the physical address.
NTP
NTP (Network Time Protocol) is used to synchronize computer clock times in a network of com-
puters.
PAN Profile
A PAN (Personal Area Network) is a network of Bluetooth devices that share the same master
unit and frequency-hopping sequence. A PAN starts with two Bluetooth connected devices and
may grow up to seven connected devices. When establishing a PAN, the AXIS 9010 will act as a
master and the devices as slaves. To insure security, authorization is needed when joining the
PAN.
