Stating a range with non-standard IP addresses?

[Timmy-P]

I'm tracking some of the IPs one of my games connects to to establish a connection to a master server.  I want to add these IPs to a firewall rule, however I'm finding that these IPs vary and not what I'd call "standard" addresses.  Take a look at the two I've found (they're non-private):

 

ec2-54-187-136-153.us-west-2.compute.amazonaws.com
ec2-54-213-198-253.us-west-2.compute.amazonaws.com

So I want to put both of them into a range, but I don't know if that would be possible.  How would I go about doing that?  Something like this?

What firewall are we talking about?

A simple access list with a permit ip 54.187.136.153 and a second permit of 54.213.198.253 should work.

Windows Firewall, because I'm cheap.

 

So I ditch the web address and just use the IPs within?

They must have a auto server pull up system on AWS.

 

They are not IP addresses they are domain names.

 

If the firewall can use domain names try this.

*.us-west-2.compute.amazonaws.com

* means wildcard so any sub domain under us-west-2.compute.amazonaws.com is effect, you may not want this though.

 

To see the ip ping the domain names in cmd and it  will put the ip in [xxx.xxx.xxx.xxx]

Use the ip/ip range for the firewall.

Yah, unless Windows Firewall needs hostnames at which point you could put in something like *compute.amazonaws.com, I haven't worked with Windows Firewall much so I don't know if it takes wildcards and whatnot

I'm whitelisting inbound connections.

Why? You said yourself that the game is establishing the connection

Because I'm an idiot, that's why.
