I am currently in the process of setting up a restricted EC2 instance where some services is whitelisted IP wise. One the service that I am trying to whitelist is gitlab. Are there any static IPs that I can use to do this?

Please i need help in using elastic IP(assigned to instance) from AWS as proxy server, the first picture shows how other people are doing it. Users on my website will use it to login to another website that requires static IP(Doesn't change). I want to know how to authenticate EC2 elastic IP and use it as proxy server, all i have so far is i need to assign elastic IP to my instance on AWS, but i don't know how to authenticate the IPs once created. And i don't want to buy static IP from other company like brightdata or smartproxy.
This picture shows how other people are doing it, and the IP is from amazon:
Does your Public IP change that often? Can you just have them give you their 'IP Chicken' address and just use that?
I think based on what you are describing you want to whitelist IPs via an ACL. Here are some steps you can use:

If you do not want to use their Public IP from wherever they are, here is another workflow:
VPN to a Bastion Host (Jump Host)
Put the Public IP you whitelist to your application on the Jump host
Require your users access the Jump Host to access the website.
You can Use Amazon Elastic IPs without issue. It is a good idea.
Public IP addresses from AWS can only be used on AWS services (eg Amazon EC2 instances). They cannot be used on external services outside of AWS.
In your picture, the IP address is assigned to an Amazon EC2 instance.
I have an application and api running/hosted in same aws ec2 instance . I have enabled ssl cert using acm via load balancer for application domain . However , my api is exposing via ec2 public ip i.e http://ec2ip. In such scenario how can I bind ssl cert in IP address i.e https://ec2ip ?
You ideally don't want to have a public IP on your load-balanced EC2. You can achieve this by placing the EC2s in a private subnet. This will need bastion server in order to SSH though.
If you absolutely want HTTPS on an IP address, this SO page is the answer. If you do set that up, make sure that it is an elastic IP address.
If you have load balance you shouldn't directly access your instance using public IP. As per AWS documentation you shouldn't even have a public IP address for your instance.
someday if you run security assessment to your aws environment, AWS Foundational Security Best Practices v1.0.0 will be failed because of public IP.
EC2 instances should not have a public IPv4 address
This all about security concerns. Typically, only a Load Balancer is exposed to the Internet.

I use Google Places API, and I need to put a restriction on my API keys, more specifically an IP restriction because the calls are from a web server.
I am using AWS Elastic Beanstalk with an environment where I have a Load Balancer, Autoscaling, and a VPC. So the IP address changes every time a new EC2 server is created.
My question is :
How do I put a static IP (Elastic ?) on my environment?
I have found many similar posts like this one (https://stackoverflow.com/a/49200693/3954420) or this one (https://medium.com/#obezuk/how-to-use-elastic-beanstalk-with-an-ip-whitelisted-api-69a6f8b5f844) where I have to create a NAT Gateway.
But it requires at the end to type a target IP address, and unfortunately, Google API servers IPs are not static.
How can I use NAT Gateway or is there another way ?
Thanks
I am trying to setup couchbase cluster on AWS. I want my nodes to be distributed across multiple availability zones.
Ec2 instances with in an availability zone are able to access each other using the ip (Private DNS) which is assigned to them during creation and which does not change even if we restart the machine.
I am not able to access an Ec2 instance from other AZ using this (Private DNS). One way this can be done is by using Elastic Ip which has a limit per region.
Question here is How to access one Ec2 instance from other EC2 instance in another AZ without elastic ip?
You do not want to use Elastic IP for this. Your statement that Elastic IP is a solution to your issue is not correct. You want to use the Private IP assigned to the instance when you created it.
The private IP will not change as long as the instances are deployed inside a VPC.
You have to use the private IP in order to keep all network traffic inside the VPC. Then you just need to make sure your Security Groups are configured correctly to allow traffic between the instances.
Amazon Web Services Operates Split-horizon DNS (AKA Split-Brain DNS). The best practice when deploying couchbase onto EC2 is to use hostnames not IP addresses, see http://developer.couchbase.com/documentation/server/current/install/cloud-deployment.html . Amazon will automatically give a different IP when resolving the hostname depending if the source of the request is internal or external.
I have a website hosted in the Amazon EC2 which calls a web service hosted locally in my personal network.
I wish to restrict access to my web service using my firewall so that only the website hosted in Amazon EC2 can access it. I don't want to open the web service up to the entire internet.
The website that is hosted in the Amazon EC2 which sits behind a load balancer. This means the ip address of my website can change at any time.
I know you can get the ip addresses via the following http://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html
But these could change and I need to update my firewall again.
How should I configure my firewall to only allow access from my website hosted in Amazon EC2 AWS?
If you have one instance on your AWS setup, you will need attach a Elastic IP. Elastic IPs are not transient and will allow you to whitelist the IP in your firewall. If you are in a VPC and your instances are in private subnet, you will need to use ELastic IPs for your NAT gateways & you will need to whitelist the NATs. Any request originating from your AWS network will use ELastic Ip as broadcast IP.
