22.2.1 DNS Server Address Assignment
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 a computer before
you can access it.
The ZyXEL Device can get the DNS server addresses in the following ways.
1
The ISP tells you the DNS server addresses, usually in the form of an information sheet,
when you sign up. If your ISP gives you DNS server addresses, enter them in the
DNS
Server
fields in the
SYSTEM General
screen.
2
If the ISP did not give you DNS server information, leave the
DNS Server
fields in the
SYSTEM General
screen set to 0.0.0.0 for the ISP to dynamically assign the DNS
server IP addresses.
22.2.2 Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or many
dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You
can also access your FTP server or Web site on your own computer using a domain name (for
instance myhost.dhs.org, where myhost is a name of your choice) that will never change
instead of using an IP address that changes each time you reconnect. Your friends or relatives
will always be able to call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is
for people with a dynamic IP from their ISP or DHCP server that would still like to have a
domain name. The Dynamic DNS service provider will give you a password or key.
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the
same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use,
for example, www.yourhost.dyndns.org and still reach your hostname.
"
If you have a private WAN IP address, then you cannot use Dynamic DNS.
