Question

Addition to /etc/hosts file

Found this in my /etc/hosts file dated 17th March

## Adobe Creative Cloud WAM - Start ##

166.117.29.222 detect-ccd.creativecloud.adobe.com

## Adobe Creative Cloud WAM - End ##

On both my Macs running Creative Cloud.

I use Lightroom Classic daily as part of a “Creative Cloud” subscription.

Just want to confirm what this is for. I’ve done some research and others have reported it as well.

Thanks

    According to this thread, the Creative Cloud has started adding this entry to the “hosts” file to allow Adobe web pages to detect whether the Creative Cloud is installed:

    That would make a lot of sense as explanation as it would be immediately clear that this file was present from the server that gets contacted without needing to do a check that a browser would block by default.

    Likely to ensure that the creative cloud app can reach it’s servers in conditions of bad network connection even when there is no active dns or to prevent man in the middle attacks where the wrong ip is resolved for creativecloud.adobe.com ?
