Significant web activity from 2x ip blocks

Hello,

I have daily report at our facility of web activity with the following ip address blocks recently that have no category, host name, or site name.

The only information listed is: AS33438 - StackPath, LLC.

Could someone please who knows or find out how-to verify who the following ip blocks/addresses belong to so I may better categorize this activity?

151.139.124.0/24

Example:

151.139.124.43

151.139.124.59

151.139.124.66

151.139.124.67

151.139.124.68

151.139.48.0/22

Example:

151.139.51.180

151.139.51.182

151.139.51.185

151.139.51.188

It looks like all the IPs belong to AS33438 StackPath, LLC. details - IPinfo.io.

Check out our summary tool as well:

Do you want the list of all the ranges they own? I can get you those IPs using our free database.

Hello,

I did see most of this info when I searched also.

So are these ip blocks Microsoft; updates, content delivery, etc?

Thank you,

Justin

Not sure about that. Stackpath is owned by IBM and it is their edge computing service.

StackPath is an American edge computing platform provider headquartered in Dallas, Texas. Its founding team was led by Lance Crosby, who also co-founded SoftLayer Technologies, acquired by IBM in 2013
