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.

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:
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:
