1. IPv6 address:
Enter the IPv6 address here; IPv6 addresses have a size of 128
bits. Therefore, IPv6 has a vastly enlarged address space compared to IPv4. An
example of an IPv6 address is
“2001:0db8:85a3:0000:0000:8a2e:0370:7334”
2. Subnet Prefix Length:
Enter the Prefix length of the Subnet Mask here; the
prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather
than being expressed in 4 octets like it is in IPv4, it is expressed as an integer
between 1 and 128. For example: 2001:db8:abcd:0012::0/64 specifies a subnet
with a range of IP addresses from: 2001:db8:abcd:0012:0000:0000:0000:0000 to
2001:db8:abcd:0012:ffff:ffff:ffff:ffff.
3. Default Gateway:
Enter the Default Gateway address here; a default gateway is
the node on the computer network that the network software uses when an IP
address does not match any other routes in the routing table.
4. Primary / Secondary DNS:
You may select to obtain DNS server address
automatically or use following DNS address. You may add IPv6 address Primary
DNS address and secondary DNS address.
5. MLD Snooping:
MLD snooping, IPv6 multicast data is selectively forwarded to a
list of ports that want to receive the data, instead of being flooded to all ports in a
VLAN. This list is constructed by snooping IPv6 multicast control packets. If
necessary in your environment, please enable this feature.
