Example: Since one server in the system can only use IPv6, all communication with that server must use IPv6.
However, that server also determines the IP version for communication between all other servers in the
system.
Writing IPv6 addresses (explained)
An IPv6 address is usually written as eight blocks of four hexadecimal digits, with each block separated by a
colon.
Example: 2001:0B80:0000:0000:0000:0F80:3FA8:18AB
You may shorten addresses by eliminating leading zeros in a block. Also, note that some of the four-digit
blocks may consist of zeros only. If any number of such 0000 blocks are consecutive, you may shorten
addresses by replacing the 0000 blocks with two colons as long as there is only one such double colon in the
address.
Example:
2001:0B80:0000:0000:0000:0F80:3FA8:18AB can be shortened to
2001:B80:0000:0000:0000:F80:3FA8:18AB if removing the leading zeros, or to
2001:0B80::0F80:3FA8:18AB if removing the 0000 blocks, or even to
2001:B80::F80:3FA8:18AB if removing the leading zeros as well as the 0000 blocks.
Using IPv6 Addresses in URLs
IPv6 addresses contain colons. Colons, however, are also used in other types of network addressing syntax. For
example, IPv4 uses a colon to separate IP address and port number when both are used in a URL. IPv6 has
inherited this principle. Therefore, to avoid confusion, square brackets are put around IPv6 addresses when
they are used in URLs.
Example of a URL with an IPv6 address:
http://[2001:0B80:0000:0000:0000:0F80:3FA8:18AB], which may of course be shortened to, for example, http://
[2001:B80::F80:3FA8:18AB]
Example of a URL with an IPv6 address and a port number:
http://[2001:0B80:0000:0000:0000:0F80:3FA8:18AB]:1234, which may of course be shortened to, for example,
http://[2001:B80::F80:3FA8:18AB]:1234
