5.3.4.10 Dynamic DNS
Dynamic DNS can map a dynamic IP address to a fixed host name, and all users
on the Internet can access the host by this host name. ISP assigns the IP
addresses by DHCP, so it is difficult for the users to search the host by DNS. For
example, if the IP address of a public Web server or VPN server is changed on the
LAN, you can still find the corresponding host by the DDNS service.
Choose Advanced Network > Dynamic DNS on the left pane or click DDNS in
the ADVANCED NETWORK page to display the following page.
