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.

Way to the Web Ltd and Configserver.com will be closing down permanently on 31 August 2025. The server software market has changed drastically in the more than 25 years since our company began, and we now find the business is no longer profitable so must come to an end.

All the details are available here.
