An IPv6 (Normal) address has the following format: y:y:y:y:y:y:y
:ywhere y is called a segment and can be any hexadecimal value between 0 and
FFFF. The segments are separated by colons - not periods. An IPv6 normal address
must have eight segments, however a short form notation can be used in the Tape
Library Specialist Web interface for segments that are zero, or those that have
leading zeros. The short form notation can not be used from the operator panel.
Examples of valid IPv6 (Normal) addresses:
v 2001 : db8: 3333 : 4444 : 5555 : 6666 : 7777 : 8888
v 2001 : db8 : 3333 : 4444 : CCCC : DDDD : EEEE : FFFF
v ::(implies all 8 segments are zero)
v 2001: db8: : (implies that the last six segments are zero)
v : : 1234 : 5678 (implies that the first six segments are zero)
v 2001 : db8: : 1234 : 5678 (implies that the middle four segments are zero)
v 2001:0db8:0001:0000:0000:0ab9:C0A8:0102 (This can be compressed to
eliminate leading zeros, as follows: 2001:db8:1::ab9:C0A8:102 )
Here is an example of a screen that uses IPv6 addresses:
Ethernet IPv6 Panel 0178

Frame 1, Port B÷

An IPv6 (Dual) address combines an IPv6 and an IPv4 address and has the
following format: y:y:y:y:y:y:x.x.x.x. The IPv6 portion of
the address (indicated with y's) is always at the beginning, followed by the IPv4
portion (indicated with x's).
v In the IPv6 portion of the address, y is called a segment and can be any
hexadecimal value between 0 and FFFF. The segments are separated by colons -
not periods. The IPv6 portion of the address must have six segments but there is
a short form notation for segments that are zero.
v In the IPv4 portion of the address x is called an octet and must be a decimal
value between 0 and 255. The octets are separated by periods. The IPv4 portion
of the address must contain three periods and four octets.
Examples of valid IPv6 (Dual) addresses:
v 2001 : db8: 3333 : 4444 : 5555 : 6666:1.2.3.4
v ::11.22.33.44(implies all six IPv6 segments are zero)
v 2001 : db8: : 123 . 123 . 123 . 123 (implies that the last four IPv6 segments
are zero)
v ::1234:5678:91.123.4.56(implies that the first four IPv6 segments
are zero)
v ::1234:5678:1.2.3.4(implies that the first four IPv6 segments are
zero)
