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 ZyXEL
Device 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 312 to reach our internal server. It is
inconvenient for the users if this IP is dynamic. With DDNS supported by the ZyXEL Device, 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 312.
When the ISP assigns the ZyXEL Device a new IP, the ZyXEL Device updates this IP to DDNS server so that
the server can update its IP-to-DNS entry. Once the IP-to-DNS table in the DDNS server is updated, the DNS
name for your web server (i.e., www.zyxel.com.tw) is still usable.
