Dynamic DNS
The
Dynamic
DNS
function
allows
you
to
alias
a
dynamic
IP
address
to
a
static
hostname,
allowing
users whose
ISP
does
not
assign
them
a
static
IP
address
to
use
a
domain
name.
This
is
especially
useful
for hosting
servers
via
your
ADSL
connection,
so
that
anyone
wishing
to
connect
to
you
may
use
your domain
name,
rather
than
having
to
use
your
dynamic
IP
address,
which
changes
from
time
to
time.
This dynamic
IP
address
is
the
WAN
IP
address
of
the
router,
which
is
assigned
to
you
by
your
ISP.
You
will
first
need
to
register
and
establish
an
account
with
the
Dynamic
DNS
provider
using
their
website, for
example
http://www.dyndns.org/
There are more than 5 DDNS services supported.

the
DDNS
service
you
have
established
an
account
with.
Domain Name, Username and Password:
Enter
your
registered
domain
name
and
your
username
and
password
provided
by
your
DDNS
service.
Period:
Set
the
time
period
between
updates.
This
is
the
interval
after
which
your
router
will
exchange
information
with
the
DDNS
server.
In
addition
to
updating
periodically
as
per
your
settings,
the
router
will perform
an
update
when
your
dynamic
IP
address
changes.
