Domain Name
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If
you leave this blank, the domain name obtained by DHCP from the ISP is used.
While you must enter the host name (System Name) on each individual computer,
the domain name can be assigned from the MAX-207HW2R via DHCP.

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.

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 MAX-207HW2R 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.

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.

9.2 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.
