These are the following types of IP address assignment.
Assign the predetermined IP address to the scanner (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 scanner, 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.
Assign the IP address automatically to the scanner (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.
We recommend managing devices other than the IP address and communicating with protocols that can follow the IP address.
When you use the IP address reservation function of the DHCP, you can assign the same IP address to the devices at any time.
