6.1.2 What You Need to Know About Network

IP Address
The NSA needs an IP address to communicate with other devices on your network. The NSA
can get an IP address automatically if you have a device on your network that gives them out.
Or you can assign the NSA a static (fixed) IP address.
DNS Server Address
A DNS (Domain Name System) server maps domain names (like www.zyxel.com) to their
corresponding numerical IP addresses. This lets you use domain names to access web sites
without having to know their IP addresses. The NSA can receive the IP address of a DNS
server automatically (along with the NSA's own IP address). You can also manually enter a
DNS server IP address in the NSA.
Jumbo Frames
Jumbo frames are Ethernet frames larger than 1500 bytes. They enable data transfer with less
overhead. The bigger the frame, the better the network performance. Your network equipment
such as computers, switches and routers must be capable of supporting jumbo frames. You
also need to enable jumbo frames in all related network devices.
PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) allows the NSA to establish a direct Internet
connection if you do not have a router. PPPoE is a dial-up connection. You need a username
and password from your Internet Service Provider (ISP) to set up the connection.
