Using the Dynamic DNS Function 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 printer, a DNS client, is connected, records can be dynamically updated using this function. Updating Updating procedure varies depending on whether the printer IP address is static or acquired by DHCP. Note ❒ When the dynamic DNS function is not used, records managed by the DNS 4 server must be updated manually, if the printer's IP address is changed. ❒ To update the record using the printer, the DNS server has to have one of the following: • No security settings made. • If security settings are made, an IP-specified client (this printer) permits updating. ❖ For a static IP setting If the IP address or host name is changed, the A and PTR records are updated. If the A record is registered, CNAME is also registered. 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) ❖ For DHCP settings As a substitute for the printer, the DHCP server updates the record, and one of the following occurs: • When the printer acquires the IP address from the DHCP server, the DHCP server updates the A and PTR records. • When the printer acquires the IP address from the DHCP server, the printer updates the A record, and the DHCP server updates the PTR record. If the A record is registered, CNAME is also registered. 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) Important ❒ Dynamic update using message authentication (TSIG, SIG(0)) is not supported. 123
