RE: IBM IP Addresses / Ports

IBM Storwize is using these IPs for call home.


If you are using DNS, allow outbound traffic over port 443 to esupport.ibm.com.

If you are not using DNS, allow outbound traffic over port 443 to the following IP addresses: 129.42.54.189, 129.42.56.189, and 129.42.60.189.

Subject: IBM IP Addresses / Ports

A couple of my customers have put requirements it to lock down
inbound/outbound communications in their firewalls to only known addresses.
I've been asked for a list of IBM IPs and ports that need to be open. I've
compiled the following list. Does anyone know of any others that I need to
add? I can't find any specific information on ESS but I suspect that's
because IBM only uses Download Director for that function. Here's the list
so far: ( I tried to format it so all the mail clients won't mess it up )
