DHCP server can also give “static” IP addresses to clients.
From the previous
configuration
file, there
is also a block that starts
with
“host boss”.
What
this does
is
it
will
look at the clients, which
will
be
named
“boss”, by
looking at the MAC address of
that particular
host.
So
if
it
matches,
it
will
give a
fix
address,
in
this
case
192.168.1.2.
Network
administrator
also
needs
to pay attention that the IP addresses that are
given
to
static
clients
must
be
out
of
the
range
that
was
previously
mentioned.
If
it
was
in
the
same range, IP address conflict might happen in the
future.
2.4.3.5 DNS
According to the earlier explanation, IP address
is
just
like a phone
number,
where there
is some form to determine its location, and then followed by unique identifier of that
particular
phone
number.
Domain
Name
System
(DNS),
is
like
putting those phone
numbers into phone book. Only in this case, DNS map out name from and to IP
addresses.
While a lot of people can remember their IP address, it is very inefficient to remember 10
IP
addresses
of
websites
that
everyone
go
to
everyday.
By
having
DNS,
it
is
easier
to
remember
website address by name.
It
is
very
natural
for our brains
to remember
names
better than
numbers.
For example, when browsing to http://iupstudent.binus.ac.id, the IP add ress can be ignore
or does
not
need
to remember
its
IP address.
Instead, DNS
will
try to connect
to other
