Hi Guys, I try to use microstacks and I would like to calculate a 3 available fix IPs 1/subnet in a VPC (in the current stack I know the vpcId), I need these IPs in different subnets. How should I do this with Pulumi? :wink: I can use 3rd party tools to achieve this goal

Pulumi is just typescript/javascript, I am sure there is abundance of NPM packages for CIDR calculations 

There actually aren’t the abundance you think there are!

At least, not necessarily that do useful things

I ended up resorting to my “own” cidr math: <https://github.com/jen20/pulumi-aws-vpc/blob/master/src/cidr.ts>

I’m not 100% sure I understand the requirement though - could you give an example, <@UEYR6QM5X>?

Guys, Thanks, I did not know there is a getVpc in the aws.ec2, I did not know it....i was looking for a module aws.vpc aws.network or something else....After I got the VPC, i can ask subnets, and of course i can choose IP

Thanks, this knowledge was needed for me...
