You can select the type of IP address to assign to the
product.
Static IP address
A static IP address is fixed and does not change when the
device connects to the network. The settings required to connect to
the network (subnet mask, default gateway, DNS server, etc.) need
to be configured manually. Use a static IP address when you want to
manage the device on a network that many computers access. Also,
when using security features such as IPsec/IP filtering, assign a
static IP address to ensure that the IP address does not
change.
Dynamic IP address
A dynamic IP address is automatically assigned to your product
by a DHCP (Dynamic Host Configuration Protocol) server whenever it
connects to a network. The settings required to connect to the
network (subnet mask, default gateway, DNS server, etc.) are 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, the IP address may change when re-connecting.
Note: If you use the IP address reservation
function of the DHCP, you can assign the same IP address to the
devices at any time.
