internet .
❏ Epson Connect Services

“Using Port for the Scanner” on page 211
IP Address Assignment
ese are the following types of IP address assignment.
Static IP address:
Assign the predetermined IP address to the scanner (host) manually.
e
information to connect to the network (subnet mask, default gateway, DNS server and so on) need to be set
manually.
e
IP address does not change even when the device is turned
o,
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 ltering, assign a xed 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 scanner (host) by using the DHCP function of the DHCP server or
router.
e 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 o, 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.
Note:
When you use the IP address reservation function of the DHCP, you can assign the same IP address to the devices at any
time.
