It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source filesĪnd the existing files in the destination. It offers a large number of options that control every aspect of its behavior and permit very flexible specification of the set of files to be copied. It can copy locally, to/from another host over any remote shell, or to/from a remote rsyncĭaemon. If you compress a series of consecutive fields of hexadecimal zeros twice in an IPv6 Address, it will be impossible to identify how many zeros and compressed in each double colon (::).Rsync is a fast and extraordinarily versatile file copying tool. Note that compressing and shortening a series of consecutive fields of hexadecimal zeros in an IPv6 Address is possible ONLY once. We can further simplify and shorten the above IPv6 Address as 2001:db8:0:b::1A. Compress consecutive hexadecimal fields of zeros using Double colon: IPv6 addresses can be further simplified by using double colons (::) in place of a series of consecutive hexadecimal zeros.įor above example 2001:db8:0:b:0:0:0:1A, we have a series of three consecutive fields of hexadecimal zeros as marked 2001:db8:0:b: 0:0:0:1A.

Omit leading zeros: For simplifying and shortening lengthy IPv6 Address, we can omit the leading zeros in any 16-bit IPv6 Address blocks.įor example, in IPv6 address 2001:0db8:0000:000b:0000:0000:0000:001A the leading zeros are marked as 2001: 0db8: 0000: 000b: 0000: 0000: 0000: 001A.Īfter removing the leading zeros, the IPv6 Address quoted above can be written as 2001:db8:0:b:0:0:0:1A.

We can further simplify shorten and compress IPv6 Addresses using following methods.Ĭonsider the IPv6 Address 2001:0db8:0000:000b:0000:0000:0000:001A as an example. IPv6 addresses often contain consecutive zeros. Somehow we need to shorten and simplify IPv6 addresses to use it with more ease in our day-to-day life.

Think about the pain in typing all those IPv6 address hexadecimal characters in any shell prompt. Consider a situation where you need to ping to an IPv6 address 2001:0db8:0000:000b:0000:0000:0000:001A to check the network connectivity. IPv6 addresses are 128 bit binary numbers (represented in hexadecimal format), which are so lengthy and difficult handle in our day-to-day life.
