How to Test for IP Address Changing for sig-repo.synopsys.com prior to May 10,
2023

As part of our relentless ongoing pursuit of maximizing the security of customer
applications and data, Synopsys is changing its security infrastructure to
ensure that we maintain a highly secure infrastructure.  Synopsys is migrating
sig-repo.synopsys.com to a new provider on May 10, 2023, which will result in an
IP address change for this site.  

 

For customers who access the site via IP address or have the IP address
configured in the network firewalls or allow lists, the current IP address NEEDS
TO BE CHANGED TO THE NEW IP ADDRESS.

 

Refer to this article for full details on notice
https://community.synopsys.com/s/question/0D52H00006SyxJ0SAJ/ip-address-changing-for-sigreposynopsyscom-on-may-10-2023.

 

To test before the cutover date, below are the steps based on a platform.

 

Summary of steps:

 1. On Mac/Linux, edit your /etc/hosts file to add this line to the
    top:  34.110.245.127  sig-repo.synopsys.com                       
 2. Run your normal build or scanning process to verify it still works OR run a
    curl command to verify the IP address is accessible.
 3. Remove the sig-repo.synopsys.com line from the /etc/hosts file after
    concluding the test.
