The McAfee Enterprise Security Manager (ESM) retrieves rule updates from www.nitroguard.com.
On August 10, 2017, the DNS entry for www.nitroguard.com will be updated from 22.214.171.124 to 126.96.36.199.
To ensure that the ESM is able to maintain communication with the rule update server, Technical Support recommends that you update your firewall configuration to allow the new rule update server IP address, 188.8.131.52, to communicate to the ESM.
