• DHCP addressing mode
DHCP addressing mode DHCP addressing mode
DHCP addressing mode – in this mode the DHCP server automatically allocates the
IP addresses to the Uniti.
• Static addressing mode
Static addressing mode Static addressing mode
Static addressing mode – in this mode the user manually allocates the IP addresses
to the Uniti. This method is more complicated to set up than DHCP and should only
be used if it has been determined that static addressing mode is necessary.
• DHCP server
DHCP serverDHCP server
DHCP server – This allocates the IP addresses to the devices on the network. In a
typical home setup the DHCP server is built into the Modem/Router.
• DHCP address pool
DHCP address poolDHCP address pool
DHCP address pool – The address pool is the range of addresses used by the DHCP
server when allocating IP addresses to devices on the network. The current DHCP
pool settings can usually be determined by checking the Modem/Router
configuration.
• DNS
DNS DNS
DNS – The Domain Name System is a system of converting a domain name (e.g.
www.naimaudio.com) to an IP address. When accessing the Internet the DNS
service is usually provided by the ISP. The local DNS server in the Mode/Router
performs the same function but on the local network.
• Software Firewall
Software FirewallSoftware Firewall
Software Firewall – A software firewall runs on a computer and prevents unwanted
intrusions from other computers. Microsoft Windows XP and Vista are both supplied
with software firewalls. Normally Windows will advise if these are not enabled.
Examples of other software firewall vendors are ZoneAlarm, Norton and Eset. It is
recommended to always run a software firewall on any computer connected to
the Internet.
• Hardware Firewall
Hardware Firewall Hardware Firewall
Hardware Firewall – Most Modem/Routers have a build in firewall, often known as a
hardware firewall. These prevent unwanted intrusions from computers on the
Internet by stopping any incoming communication not initiated from the local
network. A hardware firewall is not a substitute for a software firewall and it is
recommended that both are always used together.
• Gateway
Gateway Gateway
Gateway – This is the IP address that the Uniti uses to access the Internet. In a home
network this is often the same IP address as the Modem/Router
• IP Address

IP Address – This is the unique address of a device on a network.
• ISP

ISP – The Internet Service Provider is the company that provides the Internet
connection to the home.
• LAN
