Using The Dynamic Dns Function - Ricoh CL1000N User Manual

Using the Dynamic DNS Function

Dynamic DNS is a function which dynamically updates (registers and deletes) records (A record and
PTR record) managed by the DNS server. When a DNS server is part of the network environment to
which this machine is connected and this machine is a DNS client, records can be dynamically updated
using this function.
About processing updates
Updating procedure differs depending on whether the machine's IP address is static or acquired by DHCP.
Note
When the dynamic DNS function is not used, if the IP address of this machine is changed, records
managed by DNS server must be updated manually.
To update the record with this machine, the DNS server has to have either of the following:
• No security settings made.
• If security settings are made, an IP-specified client (this machine), that permits updating.
In the case of a static IP setting
If the IP address or host name is changed, this machine updates the A and PTR record.
If the A record is registered, CNAME is registered also. CNAMEs that can be registered are as follows.
• Ethernet and IEEE 802.11b
RNPXXXXXX (XXXXXX represents the last 3 hexadecimal bytes of the MAC address)
