5.1.2 What You Need to Know About Network Deployment

LAN
A Local Area Network (LAN) is a shared communication system to which many computers
are attached. A LAN, as its name implies, is limited to a local area.
WAN
WANs link geographically dispersed locations in other cities or around the globe including
switched and permanent telephone circuits, terrestrial radio systems and satellite systems.
DNS
Use DNS (Domain Name System) to map a domain name to its corresponding IP address and
vice versa. For instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is
extremely important because without it, you must know the IP address of any network device
before you can access it.The ISP (or network administrator) should tell you the DNS server
addresses, usually in the form of an information sheet, when you sign up.
DDNS
Dynamic DNS maps your dynamic IP address to a static domain name. You can have a static
hostname alias for a dynamic IP address, allowing the host to be more easily accessible from
various locations on the Internet. You must register for this service with a Dynamic DNS
service provider to use this service.
NTP
Network Time Protocol allows devices to synchronize their time setting with an external time
server.
Static Routes
When you configure static routes on the X6004, you are informing the X6004 about how to
reach networks and devices that are not reachable via the default gateway.
VLANs
Virtual Local Area Networks, standardized as IEEE 802.1Q, allow a physical network to be
partitioned into various logical networks. Only stations on the same logical network can
intercommunicate.
5.1.3 Before You Begin
Before you deploy the X6004, you should consider the following:
• If the X6004 has dynamically assigned IP address from your ISP, then you should
configure DDNS (Dynamic DNS). This allows the IP devices on the WAN to establish
connections with the X6004.
