Amazon API Gateway now helps dual-stack (IPv4 and IPv6) endpoints

Right now, we’re launching IPv6 help for Amazon API Gateway throughout all endpoint varieties, customized domains, and administration APIs, in all business and AWS GovCloud (US) Areas. Now you can configure REST, HTTP, and WebSocket APIs, and customized domains, to simply accept calls from IPv6 purchasers alongside the prevailing IPv4 help. You too can name API Gateway administration APIs from dual-stack (IPv6 and IPv4) purchasers. As organizations globally confront rising IPv4 handle shortage and growing prices, implementing IPv6 turns into essential for future-proofing community infrastructure. This dual-stack strategy helps organizations preserve future community compatibility and increase world attain. To be taught extra about dualstack within the Amazon Internet Providers (AWS) surroundings, see the IPv6 on AWS Documentation.

Creating new dual-stack sources

This put up focuses on two methods to create an API or a website identify with a dualstack IP handle sort: AWS Administration Console and AWS Cloud Improvement Equipment (CDK).

AWS Console

When creating a brand new API or area identify within the console, choose IPv4 solely or dualstack (IPv4 and IPv6) for the IP handle sort.

As proven within the following picture, you’ll be able to choose the dualstack possibility when creating a brand new REST API.
For customized domains, you’ll be able to equally configure dualstack as proven within the subsequent picture.

If it’s essential revert to IPv4-only for any purpose, you’ll be able to modify the IP handle sort setting, without having to redeploy your API for the replace to take impact.

REST APIs of all endpoint varieties (EDGE, REGIONAL and PRIVATE) help dualstack. Personal REST APIs solely help dualstack configuration.

AWS CDK

With AWS CDK, begin by configuring a dual-stack REST API and area identify.

const api = new apigateway.RestApi(this, "Api", {   restApiName: "MyDualStackAPI",   endpointConfiguration: {ipAddressType: "dualstack"} }); const domain_name = new apigateway.DomainName(this, "DomainName", {   regionalCertificateArn: 'arn:aws:acm:us-east-1:111122223333:certificates/a1b2c3d4-5678-90ab',   domainName: 'dualstack.instance.com',   endpointConfiguration: {     varieties: ['Regional'],     ipAddressType: 'dualstack'   },   securityPolicy: 'TLS_1_2' }); const basepathmapping = new apigateway.BasePathMapping(this, "BasePathMapping", {   domainName: domain_name,   restApi: api });

IPv6 Supply IP and authorization

When your API begins receiving IPv6 site visitors, consumer supply IPs will probably be in IPv6 format. When you use useful resource insurance policies, Lambda authorizers, or AWS Identification and Entry Administration (IAM) insurance policies that reference supply IP addresses, be sure they’re up to date to accommodate IPv6 handle codecs.

For instance, to allow site visitors from a selected IPv6 vary in a useful resource coverage.

{   "Model": "2012-10-17",   "Assertion": [     {       "Effect": "Allow",       "Principal": "*",       "Action": "execute-api:Invoke",       "Resource": "execute-api:stage-name/*",       "Condition": {         "IpAddress": {           "aws:SourceIp": [             "192.0.2.0/24",             "2001:db8:1234::/48"           ]         }       }     }   ] }

Abstract

API Gateway dual-stack help helps handle IPv4 handle shortage and prices, adjust to authorities and business mandates, and put together for the way forward for networking. The dualstack implementation offers a easy transition path by supporting each IPv4 and IPv6 purchasers concurrently.

To get began with API Gateway dual-stack help, go to the Amazon API Gateway documentation. You’ll be able to configure dualstack for brand new APIs or replace present APIs with minimal configuration adjustments.
