hello my name is Mika and I'm a cloud
support engineer here at the AWS Sydney
office sometimes customers ask me define
the certain static IP address on my easy
to insert I tell them that short answer
is no but let me explain you why when
ec2 instance is launched the primary
elastic network interface eni is
assigned with a reserved private IP
address from the default VPC dhcp pool
unless an IP address then has been
assigned to the ena at the instance
launch will now to an interest launch
and I'll show you the steps or the step
where you can find this IP address I'm
already signed in into AWS management
console and from here I'm opening either
to and from the console and on launch
menu instance we are selecting a Windows
2012 bays from the list I'll go with an
RT to medium you can select whichever in
stop your prefer to we advanced to
configure instance details step 3 in
configure instance details if you scroll
down to network interfaces here is where
you can have sign add the address the
none of which ever you want from the up
our pool or you can go forward and let
the system address on the IP address the
private IP address stays assigned to the
DNI until it's deleted the instances
primary ni cannot be removed
it says assigned to the instance until
the instance is deleted also it is not
possible to remove or change the primary
IP address of the primary eni but it is
possible to add more private IP
addresses to the e ni I have open
another window which shows easy to
interests that I have already running on
my BBC over here I have selected a one
of my instances on the BBC and I'm
selecting from the description out of
the window on the below
network interfaces Ethernet 0 and from
here I'm selecting the in elastic
network interface attached to the
instance now in this section I can see
the details and I can also through
actions manage IP addresses here I can
say that there's already an assigned
static IP address and I can add
additional IP address through the
console and will be later on visible in
our instance you can manually assign a
static IP addresses for your windows
network adapter but if the en eyes the
IP address and the windows network
adapters IP address do not match the
network connection won't work in some
cases you need to private IP addresses
for your windows let's book adapter and
you need to set up static IP addresses
so know for your network adapter let's
take a look at that I'm now connected to
the easy 2 inches overall AP connection
and we head on to the N windows network
adapters to assign second IP address we
open from the n system tray menu or the
network and sharing center from here we
change adapter settings in adaptive
settings the open properties we go to
Internet Protocol version 4 now in
network adapter properties I'm ready to
insert the IP addresses for this en I I
have already copied in an IP addresses
on a note that and I will now insert the
primary IP address which is 1 7 2 3 1 0
3 1 manually to this in a network
interface
and I'm inserting DN network mask and
for the softness that I have which is
too far five two five five two five five
and zero the gate therefore they send on
subnet I know that it is our normal
gateway one seven two three one zero one
for my surpluses in this case I'll go to
advanced
I need advanced I add additional IP
address which build with these the
second IP address for this eni one seven
zero three one zero four zero and once
again mask 255 two five five two five
five zero I have two settings
I close the properties to let the
configuration part through we are losing
the connectivity because the are the
accesses are find now if we go and see
the network and adapter properties we
can see in properties as we have the
primary IP address through advantage
that we have the cemetery rd address now
we can do a simple ping test we go to
start open command prompt C and B and we
can do simple ping test on the primary
IP address which is successful and to
the secondary IP address it's also
successful for more information about
the network interfaces with windows see

watching and happy cloud computing from
