address
In the
data, the suffix address is an IPv6 address encoded in network order
(high-order octet first). There must be exactly enough octets in this field to
contain a number of bits equal to 128 minus prefix length, with 0 to 7 leading
pad bits to make this field an integral number of octets. Pad bits, if present,
must be set to zero when loading a zone file and ignored on reception. For
example:
2001:0:734c:c0::

Data is the

You can omit leading zeros in sets and omit a value in a set if the value of
the set is zero.

You cannot

when you want the outside world to know a single, easily remembered name. You
can also use aliases when a host changes its name. In that case, ensure that
you have a CNAME pointer so that when people use the original name, it can be
resolved to the newer one.
