ConfigServer IP Addresses


To ensure that your server can contact ours for product version checks, upgrades and (where relevant) licensing, the following IP addresses should be whitelisted in any firewall for outbound TCP connections to ports 80 and 443:
  • 54.36.165.115 # download2.configserver.com
  • 94.130.90.175 # download.configserver.com
  • 66.165.246.166 # license.configserver.com
  • 2604:4500:9:156::6 # ipv6.license.configserver.com

This list is also available in a plain text file and a csf advanced allow filter file.
