What Is Bootp/Dhcp; What Is Ddns - ZyXEL Communications Prestige 320W Support Notes

P320W Support Notes

What is BOOTP/DHCP

BOOTP stands for Bootstrap Protocol. DHCP stands for Dynamic Host Configuration Protocol. Both are
mechanisms to dynamically assign an IP address for a TCP/IP client by the server. In this case, the
Prestige Internet Access Sharing Router is a BOOTP/DHCP server. Win95 and WinNT clients use DHCP
to request an internal IP address, while WFW and WinSock clients use BOOTP. TCP/IP clients may
specify their own IP or utilize BOOTP/DHCP to request an IP address.

What is DDNS

The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname, allowing your
computer to be more easily accessed from various locations on the Internet. To use the service, you must
first apply an account from several free Web servers such as WWW.DYNDNS.ORG.
Without DDNS, we always tell the users to use the WAN IP of the Prestige to reach our internal server. It
is inconvenient for the users if this IP is dynamic. With DDNS supported by the Prestige, you apply a
DNS name (e.g., www.zyxel.com.tw) for your server (e.g., Web server) from a DDNS server. The outside
users can always access the web server using the www.zyxel.com.tw regardless of the WAN IP of the
Prestige.
