2.1.2 IP address setting order
0025-9524
Following is described on condition that each protocol is set to on.
IP address setting order
- At startup, if [DHCP/BOOTP] in user data is set to on, it enables a user to obtain IP Address.
- At startup, if [RARP] in user data is set to on, it enables a user to obtain IP Address.
- If automatic obtainment of IP Address fails, a network works with the IP Address specified at [IP Address] in user data.
- At startup, if [Automatic address obtainment] in user data is set to off, a network works with the data specified at [IP Address], [Subnet Mask], [Default Gateway],
or [DNS Server] in user data.
- If automatic obtainment of IP Address fails or if IP Address specified at [IP Address] in user data is 0.0.0.0, IP Address can be set by either ARP method or Canon
Configuration Protocol V3 method. If data of [Network setting] in user data are changed, the change becomes effective after the power is turned off and on.

Hierarchy Protocol Protocol Outline
Network layer ARP Address Resolution Protocol This is used to obtain MAC address of device from IP address
RARP Reverse Address Resolution Protocol This is used to obtain IP address of device from MAC address.
IP Internet Protocol This is a number (no overlaps) to identify own device or other device on the
network.
ICMP Internet Control Message Protocol This is used to return error to the source when IP transmission trouble
occurs.
This is used to reply to ping command or others.
Transport layer TCP Transmission Control Protocol This is a connection type protocol on the IP.
A system to check transmitted data is incorporated.
UDP User Datagram Protocol This is a connection-less type protocol on the IP.
This is lower in credibility compared with TCP, but is used in DHCP or
SNMP, as the processing uses less memory.
