This page allows you to configure IP filters. IP filters restrict access to the printing
system based on the IP addresses and protocols.
Specify the IP addresses or network addresses of the hosts to which access is granted.
If nothing is specified on this page, access from all hosts is allowed.
IP Address
Assigns an IPv6 address to the printing system network
component.
The format of the IPv6 address is a sequence of numbers
(128 bit in total) separated by colons, e.g.
2001:db8:3c4d:15::1a2c:1a1f.
Prefix
Length
Specifies the IPv6 prefix length. It can be a decimal value
between 1 and 128.
RA
(Stateless)
Select On to use RA instead of the DHCP server to
configure IPv6 addresses.
Default
Gateway
Specifies the IPv6 address of the default gateway.
DHCPv6
(Stateful)
Specifies whether or not to obtain IPv6 IP addresses by
automatic configuration. When RA is turned On, the IP
addresses and server information are obtained via DHCPv6
based on the settings of the automatic configuration made
under RA (router setting).
Domain
Name
Specifies the DNS (Domain Name System) name of the
domain to which the printing system belongs.
DNS
Servers
(Primary,
Secondary)
Specifies the IP addresses of the primary and secondary
DNS (Domain Name System) servers. When DHCPv6
(Stateful) is turned On, you can select to use either the DNS
servers obtained via DHCP or the DNS servers being set
under this item.
