3.2.1
Identifying
an
Available
IP
Address
To
set
a
static
IP
address,
first
identify
an
IP
address
outside
the
range
of
IP
addresses
assigned
by
your
DHCP
server.
This
range
is
known
as
the
"DHCP
Scope".
3.2.2
Obtaining
Additional
Network
Information
Once
an
IP
address
has
been
identified,
confirm
that
you
have
all
the
required
network
information:
Subnet
Mask
–
The
subnet
mask
defines
the
network
and
host
portions
of
your
IP
address.
For
example,
the
default
Class
C
subnet
mask
is
255.255.255.0.
Default
Gateway–
The
default
gateway
allows
communication
to
travel
from
one
network
or
subnet
to
another.
A
default
gateway
is
usually
the
IP
address
of
a
router
or
firewall.
Network
Address–
A
network
address
defines
the
IP
address
of
your
entire
network.
It
is
usually
the
first
IP
address
on
a
given
network
or
subnet.
A
typical
Class
C
network
address
is
192.168.1.0.
Broadcast
Address–
A
broadcast
address
is
the
IP
address
used
to
broadcast
a
message
to
every
host
on
a
given
network.
It
is
usually
the
last
IP
address
on
any
given
subnet.
DNS
Server–
This
server
resolves
fully
qualified
domain
names
to
IP
addresses.
Local
DNS
Servers
are
the
best
option.
Public
DNS
servers
reside
on
the
Internet.
One
example
for
the
public
IP
address
of
a
DNS
Server
is
4.2.2.1.

3.2.3
Availability
of
DNS
Service
If
your
network
does
not
have
a
functional
DNS
server,
or
the
DNS
configuration
manually
programmed
into
the
Fonality
Phone
System
is
invalid,
the
Fonality
Phone
System
will
not
be
able
to
connect
to
Fonality's
Data
Center.
You
can
resolve
this
issue
by
using
the
IP
address
of
a
locally
available
DNS
server
or
a
public
DNS
server
in
your
configuration
(i.e.
4.2.2.2
or
4.2.2.1).
Your
phones
must
use
the
Fonality
Phone
System
as
their
Primary
DNS
Server.
Configure
your
DHCP
server
to
distribute
the
IP
address
of
the
Fonality
Phone
System
as
the
Primary
DNS
server.
If
you
are
unable
to
set
the
Fonality
Phone
System
as
the
primary
DNS
server,
your
phones
will
not
function
properly.
