Based on the above the table, the same IPv6 address before can be written in decimal
form such as:
FECE:BC23:0000:0000:0000:0000:CB34:200C
to be:
1111 1110 1100 1110 1011 1100 0010 0011 0000 0000 0000 0000 1100 1011 0011

2.4.3.1 IPv6
Prefixes
An
IPv6
prefix
is
a
similar
implementation
of
subnet
mask
in
IPv4. Instead
of
using
a
dotted decimal such as 255.255.255.0, IPv6 only
uses prefix
length
that are
represented
by
IPv6
address/n
where
n
is
the
length
of
the
prefix.
IPv4
also
support
this
type
of
prefix.
For example, a
netmask of 255.255.255.0
is similar
to
/24 because there
are
24
bits that consist of 1.
