Dynamic
IP
addresses
are
granted
only
when
your
Raven
‐
E
is
connected
and
can
change
each
time
the
modem
reconnects
to
the
network.
•
Static
IP
addresses
are
granted
the
same
address
every
time
your
Raven
‐
E
is
connected
and
are
not
in
use
when
your
modem
is
not
connected.
Since
many
cellular
providers,
like
wire
‐
based
ISPs,
do
not
offer
static
IP
addresses
or
static
address
accounts
cost
a
premium
vs.
dynamic
accounts,
Sierra
Wireless
AirLink
Solutions
developed
IP
Manager
to
work
with
a
Dynamic
DNS
server
to
receive
notification
from
Sierra
Wireless
AirLink
modems
to
translate
the
modem’s
dynamic
IP
address
to
a
fully
qualified
domain
name.
Thus,
you
can
contact
your
Raven
‐
E
directly
from
the
Internet
using
a
domain
name.
Understanding Domain Names
A
domain
name
is
a
name
of
a
server
or
device
on
the
Internet
which
is
associated
with
an
IP
address.
Similar
to
how
the
street
address
of
your
house
is
one
way
to
contact
you
and
your
phone
number
is
another,
both
the
IP
address
and
the
domain
name
can
be
used
to
contact
a
server
or
device
on
the
Internet.
While
contacting
you
at
your
house
address
or
with
your
phone
number
employ
different
methods,
using
a
domain
name
instead
of
the
IP
address
actually
uses
the
same
method,
just
a
word
based
name
is
commonly
easier
to
remember
for
most
people
than
a
string
of
numbers.
Understanding
the
parts
of
a
domain
name
can
help
to
under
‐
stand
how
IP
Manager
works
and
what
you
need
to
be
able
to
configure
the
modem.
A
fully
qualified
domain
name
(FQDN)
generally
has
several
parts.
•
Top
Level
Domain
(TLD):
The
TLD
is
the
ending
suffix
for
a
domain
name
(.com,
.net,
.org,
etc.)
•
Country
Code
Top
Level
Domain
(ccTLD):
This
suffix
is
often
used
after
the
TLD
for
most
countries
except
the
US
(.ca,
.uk,
.au,
etc.)
•
Domain
name
:
This
is
the
name
registered
with
ICANN
(Internet
Corporation
for
Assigned
Names
and
Numbers)
or
the
registry
for
a
the
country
of
the
ccTLD
(i.e.
if
a
domain
is
part
of
the
.ca
TLD,
it
would
be
registered
with
the
Canadian
domain
registry).
It
is
necessary
to
have
a
name
registered
before
it
can
be
used.
•
Sub
‐
domain
or
server
name
:
A
domain
name
can
have
many
sub
‐
domain
or
server
names
associated
with
it.
Sub
‐
domains
need
to
be
registered
with
the
domain,
but
do
not
