can we get public subnets IP of range /28?

Question

Hello Team,

We are opting couple of times Elastic IP and reserving them, similarly can we we get public ip subnet range of /28?.(if yes then how much time it would take and what would be the cost)

We dont want our subnet IP to redirect via NAT or IG. Ideally, If we need to make subnet as public then we can use Internet gateway (IG) instead of NAT so that our subnet would be public. But due to some other reason we dont want to opt this option.

We have designed one flow to connect to on Premise server  is like VPC -- Public subnet-->Private virtual interface -->direct connect --> On Premise server.
Due to SCTP protocol restriction we dont want translation of IPadress and we are looking to opt public subnet ip range.

Thank you!.
Regards.
Priti

If you have Premium Support, you can request a contiguous block of Elastic IP addressed by submitting a support ticket to AWS Support - VPC team. The pricing info is here https://aws.amazon.com/ec2/pricing/on-demand/.

Answer

Using a non-RFC 1918 CIDR block in your VPC does not make your VPC, subnets, or resources publicly accessible. Resources will still need an Elastic IP or public IP associated and a route to an IGW to be accessible publicly. As mentioned before you can request a contiguous bock of EIPs with a support ticket.

If you are accessing your VPC resources via Direct Connect and Private VIF you can absolutely use non-RFC 1918 VPC CIDR block to access via VGW.
