Using the Dynamic DNS Function Using the Dynamic DNS Function Dynamic DNS is a function which dynamically updates (registers and deletes) records (A record, AAAA record, CNAME, 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. • Dynamic update using message authentication (TSIG, SIG(0)) is not supported. For a static IPv4 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 Wireless LAN RNPXXXXXX (XXXXXX represents the last 3 hexadecimal bytes of the MAC address) However, if CNAME (RNPXXXXXX) overlaps with the host name, CNAME will not be registered. For DHCPv4 settings As a substitute for the printer, the DHCP server updates the record, and one of the following occurs: 8 • 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 Wireless LAN RNPXXXXXX (XXXXXX represents the last 3 hexadecimal bytes of the MAC address) For IPv6 settings This printer updates the AAAA record and PTR record. It also registers CNAME when the AAAA record is updated. When a stateless address is newly set, it is automatically registered on the DNS server also. • When the dynamic DNS function is not used, records managed by the DNS 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: 181
