DDNS
Dynamic
DNS
or
DDNS
is
a
term
used
for
the
updating
in
real
time
of
Internet
Domain
Name
System
(DNS)
name
servers.
We
use
a
numeric
IP
address
allocated
by
Internet
Service
Provider
(ISP)
to
connect
to
Internet.
The
address
may
either
be
stable
("static"),
or
may
change
from
one
session
on
the
Internet
to
the
next
("dynamic").
However,
a
numeric
address
is
inconvenient
to
remember
and
an
address
which
changes
unpredictably
makes
connection
impossible.
The
DDNS
provider
allocates
a
static
host
name
to
the
user.
Whenever
the
user
is
allocated
a
new
IP
address
it
is
communicated
to
the
DDNS
provider
by
software
running
on
a
computer
or
network
device
at
that
address.
The
provider
distributes
the
association
between
the
host
name
and
the
address
to
the
Internet's
DNS
servers
so
that
they
may
resolve
DNS
queries.
The
result
is
uninterrupted
access
to
devices
and
services
whose
numeric
IP
address
may
change
is
maintained.

Virtual
Server
The
Virtual
Server
feature
grants
Internet
users
access
to
services
on
your
LAN.
It
is
useful
for
hosting
online
services
such
as
FTP,
Web,
or
game
servers.
For
each
Virtual
Server,
you
define
a
WAN
port
on
your
router
for
redirection
to
an
internal
LAN
IP
Address.
