  • Added the following Europe, Middle East, and Africa IP addresses: 18.200.102.222, 34.245.253.161, 18.200.177.198, 3.248.4.201, 52.16.112.58, 54.72.18.197, 34.254.121.67, 63.35.83.224
  • Added the following Asia Pacific IP addresses: 13.113.20.59, 3.113.144.18, 3.113.179.87, 52.194.198.2, 52.69.144.176, 52.69.3.12, 3.113.200.66, 3.113.68.241

IP addresses can change, so McAfee recommends the use of a fully qualified domain name (FQDN) that returns a list of active endpoints at the nearest Cloud Point of Presence (PoP).

Access to Global Threat Intelligence (GTI) is configured on port 443 using an FQDN so that a DNS lookup can return the nearest and most accurate IP address records at any given time. This returned result can be any of several IP addresses across the globe. Because the exact IP address is not known in advance, firewall administrators must open port 443 outbound globally. If the firewall does not support configuring an open port against a host name, or if organizational security policies do not allow it, a specific GTI IP address must be used.

GTI is hosted as a global cloud service, so hard coding an IP address could result in an outage for one of the following reasons:
  • That particular IP address is taken out of service for maintenance.
  • A network outage segments a static path to a given IP address in a given data center.
  • The data center host changes.
The preferred configuration method is to configure access to the GTI servers to use port 443 to the FQDN.

NOTE: The FQDN depends on the product, which requires you to see the product documentation for your installed product.

Solution

How to obtain a list of the current GTI IP addresses
Use one of the following to look up the FQDN using either nslookup for Windows systems, or a dig for *nix-based systems. 
 
NOTES:
  • The IP address list is pulled from the Global Traffic Management (GTM) system and represents the active endpoints at the nearest PoP at the time of the lookup.
  • Generally, these IP addresses do not change over time, but that is not the same as saying that they will never change over time or that they will always be available or in-service. McAfee has no procedures in place to proactively notify customers regarding internal IT changes and maintenance.
  • McAfee provides this information to simplify the process for our customers to look up the list periodically on their own schedule. If the host name resolves to IP addresses and an open port 443 in your firewall, periodically check the list of IP addresses and make sure that there have been no changes. Changes could impact the performance and operation of various products that must communicate with GTI.

If the security policy of an organization allows it, and network administrators would prefer to create rules around netblocks used for the GTI Cloud, they can use the following CIDR blocks:
 
GTI Cloud Netblocks
8.18.25.0/25
8.21.161.0/25
161.69.92.0/25
161.69.165.0/25
161.69.169.0/25
161.69.199.0/25
161.69.226.0/25

These netblocks are subject to change in the future, but would allow for more blanket coverage and one-time Access Control List configuration.

Additional configuration details
In addition to the above netblocks, in 2016 McAfee began using Public Cloud resources to augment the GTI Cloud. In 2018 and again in 2019 that usage was expanded, and a client might be directed to a GTI Cloud PoP in the Public Cloud. The current IP address list for those resources is as follows.
