System > Network> Advanced Network > DDNS
By configuring a DDNS, you can resolve fixed domain names to dynamic IP addresses.
In the DDNS page, you can perform the following actions:
Options in the DDNS Configuration dialog:
| Option | Description |
| DNNS Name |
Specifies the name of DDNS. |
| Interface |
Specifies the interface to which DDNS is applied. |
| Hostname |
Specifies the domain name obtained from the DDNS provider. |
| Provider |
Specifies a DDNS provider. Choose one from the drop-down list. |
| Server Name |
Specifies a server name for the configured DDNS. |
| Server Port |
Specifies a server port number for the configured DDNS. The value range is 1 to 65535. |
| User |
Specifies the username registered in the DDNS provider. |
| Password |
Specifies the corresponding password. |
| Confirm Password |
Enter the password again to confirm. |
| Minimum Update Interval |
When the IP address of the interface with DDNS enabled changes, the system will send an update request to the DDNS server. If the request is not responded, the system will send the request again according to the configured min update interval. For example, if the min update interval is set to 5 minutes, then the system will send the second request 5 minutes after the first request failure; if failed again, the system will send the request again 10 (5x2) minutes later; and 20 (10x2) minutes later, so and forth. The value will not increase anymore when reaching 120, that is, the system will send the request at a fixed interval of 120 minutes. Type the min update interval into the box. The value range is 1 to 120 minutes. The default value is 5. |
| Maximum Update Interval |
On the condition that IP address has not changed, the system will send an update request to the DDNS server at the max update interval. Type the max update interval into the box. The value range is 24 to 8760 hours. The default value is 24. |
