IPv6 addresses
IPv6 addresses consist of 8 fields each with four-character hexadecimal numbers (128
bits in total). The fields are separated by a colon, refer to the section "Structure of an IPv6
address (Page 51)".
Network masks
A network mask is a series of bits that describes the network part of an IPv4 address.
The notation is normally decimal in keeping with the IPv4 address.
Alternative notation for network masks
In contrast to the notation described above, network masks can also be represented as a
number of 1 bits. The mask of the decimal representation 255.255.0.0 is then written as
/16.
The syntax is then for example: <ipaddress> / 16
Note that there must be a space before and after the "/".
MAC addresses
In the syntax of the Command Line Interface, a MAC address is represented as a
sequence of 6 bytes in hexadecimal format, in each case separated by a colon.
The syntax is then, for example: aa:aa:aa:aa:aa:aa
Multicast addresses
Layer 2 multicast addresses as used on this device use the notation of MAC addresses.
For permitted address ranges, check the rules or ask your network administrator.
