Ipv6 address too long if we written in the same as the Ipv4 format-
124.123.045.123.123.123.089.255.346.123.234.127.213.234.123.123
there are three conventional form for representing Ipv6 addresses as text string:
the preferred form is x:x:x:x:x:x:x:x, where the 'x' are the hexadecimal values
of the eight 16-bit places of the address.
Example:
FE12:4567:3C23:4984:0011:0000:0000:0006 or
1001:0:0:5:ED12:7:4567:0
note that is not necessary to write leading zeros in an individual field, but there must be at least one numeral in every field.
abbreviated form -Blocks of continuous zeros can be abbreviated
Example:
1001:0000:0000:0000:0000:D578:0000:0000 (preferred form)
1001::D578:0:0 or 1001:0:0:0:0:D578:: (abbreviated form)
The use of "::" indicates multiple groups of 16-bits of zeros. The "::" can only
Appear once in an address.
1001::D578:: (not acceptable)
the alternative form when dealing with mixed environment of Ipv4 and Ipv6 nodes
is: x:x:x:x:x:x:d:d:d:d, where the 'x's are the hexadecimal value and the 'd's are the decimal values.
Example:
0:0:0:0:0:0:12.127.65.3 or in compressed form ::12.127.65.3 .
for IPv4 node the address are 12.127.65.3 .
for IPv6 node the address are ::12.127.65.3 .
