Public IP address list for VMware vCenter Server (IP Addresses of dl.broadcom.com)

Products

• VMware vSphere ESXi

Issue/Introduction

This article provides information on the fixed IP addresses used to serve VMware vCenter Server.  Users can utilize the IP list as the destination in external proxy and firewall outbound rules.

Environment

• VMware vSphere 7.x
• VMware vSphere 8.x
• VCF 9.x

Cause

In some environments, firewall blocks outbound connections to arbitrary IPs for security concerns. This prevents VMware vCenter Server from connecting to dl.broadcom.com. that can lead to timeout errors during patching activities.

Resolution

VMware vCenter Server connects to dl.broadcom.com to download updates.
dl.broadcom.com is provided through content delivery network (CDN) which significantly improves its download performance. Due to the scale and distributed nature of CDN, in the past it was not possible to host dl.broadcom.com on a fixed list of IP addresses.

VMware by Broadcom has announced that dl.broadcom.com is now being hosted on a fixed list of public IP addresses on CDN.

Public IP List

IPv4	IPv6
162.159.140.167	2a06:98c1:58::a5
172.66.0.165	2606:4700:7::a5

Users can use the IP list and TCP port 80, 443 as allowed destination for external proxy and firewall outbound rules. This allows VMware vCenter Server to connect to dl.broadcom.com to download patches.
