IP Address Assignment
These are the following types of IP address assignment.
Static IP address:
Assign the predetermined IP address to the printer (host) manually.
The information to connect to the network (subnet mask, default gateway, DNS server and so on) need to be set
manually.
The IP address does not change even when the device is turned off, so this is useful when you want to manage
devices with an environment where you cannot change the IP address or you want to manage devices using the IP
address. We recommend settings to the printer, server, etc. that many computers access. Also, when using security
features such as IPsec / IP filtering, assign a fixed IP address so that the IP address does not change.
Automatic assignment by using DHCP function (dynamic IP address):
Assign the IP address automatically to the printer (host) by using the DHCP function of the DHCP server or
router.
The information to connect to the network (subnet mask, default gateway, DNS server and so on) is set
automatically, so you can easily connect the device to the network.
If the device or the router is turned off, or depending on the DHCP server settings, IP address may change when
re-connecting.
