IPv6
The IP address range of IPv4 features a potential 4294 967 296 addresses but is
barely sufcient for today’s network age. A larger Internet protocol was therefore
produced a number of years ago. The address size is 128 bits compared with
IPv4 which has 32 bits.
IPv6 addresses are usually written in hexadecimal (IPv4: decimal) where the
number is broken down into eight blocks of 16 bits each (four hexadecimal
points). These blocks are listed separately using colons (IPv4: full stops).
Example: 1475:0000:8233:04a3:1000:806e:0300:7368
If the IP address contains several zeros one after another in a segment, they can
be replaced by one single zero.
Example: 1475:0:8233:04a3:10:806e:030:7368
If the IP address contains several blocks of zeros, they can be replaced by two
colons one after another.
Example: 1475:0:0:0:0:806e:030:7368 = 1475::806e:030:7368
This scenario is only permitted once per IP address. The following example is not
permitted.
Example: permitted: 1475:0:00:23ad:0:0:030:7368 =
1475::23ad:0:0:030:7368
Not permitted: 1475:0:00:23ad:0:0:030:7368 = 1475::23ad::030:7368
The last four bytes of the address can use the standard decimal notation.
::ffff:127.0.0.1 is therefore an alternative way of writing ::ffff:7f00:1. This form is
used especially when embedding the IPv4 address space in the IPv6 address space.
Jabber
The Jabber messaging protocol is a process used in Ethernet networks that
prevents one station from occupying the transmission medium for too long.
Collision
A collision is said to occur when two or more stations transmit in a shared data
channel at the same time. Because the transmitted data overlaps, it is unusable.
Collision domain
A collision domain is a segment of a CSMA/CD network.
Ethernet networks according to IEEE 802.3 contain all end devices in a physical
Ethernet segment (including those which are linked via a repeater) in the same
collision domain.
