You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the
ISP can provide you with the Internet addresses for your local networks. On the other hand, if
you are part of a much larger organization, you should consult your network administrator for
the appropriate IP addresses.
"
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
6.6 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, manually enter them in
the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the ZyXEL
Device’s WAN IP address), set the DNS server fields to get the DNS server address from
the ISP.
3 You can manually enter the IP addresses of other DNS servers. These servers can be
public or private. A DNS server could even be behind a remote IPSec router (see
).
6.7 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
You can configure the WAN port's MAC address by either using the factory default or cloning
the MAC address from a computer on your LAN. Once it is successfully configured, the
address will be copied to the "rom" file (ZyNOS configuration file). It will not change unless
you change the setting or upload a different "rom" file.
