What is the IP for Contrast SaaS?

Question

What are the IP addresses or domains for the Contrast SaaS instances?

Answer

For inbound traffic to the Contrast SaaS instance:

• From 1st November 2021:
  The following static IPs are used for all Contrast SaaS instances:

  151.101.2.246	151.101.2.232
  151.101.66.246	151.101.66.232
  151.101.130.246	151.101.130.232
  151.101.194.246	151.101.194.232

• Prior to 31st October 2021:
  An AWS Elastic Load Balancer is used, meaning the IP Range is dynamic. As such, the Contrast Cloud Engineering team recommends binding to the DNS entry (eg. app.contrastsecurity.com), if that is an option for your firewall. However, if that isn't an option, AWS allows you to filter to the correct range, as described here: AWS IP address ranges

  Contrast SaaS UI	AWS Region	Services
  app.contrastsecurity.com	us-east-1	EC2, CLOUDFRONT
  app.contrastsecurity.jp	ap-northeast-1	EC2, CLOUDFRONT
  cs001.contrastsecurity.com	us-west-2	EC2, CLOUDFRONT
  eval.contrastsecurity.com	us-east-1	EC2, CLOUDFRONT

For outbound traffic: from our SaaS instance, required for bugtracker integrations, we have the following static IPs:
