Zoom IPRange are obsolete

Hi,

Twice this week, we (IT Infrastructure department) have been called for excessive Zoom Filtering.

Despite this url:

https://support.zoom.us/hc/en-us/articles/201362683-Zoom-network-firewall-or-proxy-server-settings#h_01EJHWF2FSMCD2HFEPMQJMKAM4

we discovered that we need to maintain a special list  with:

Non-authoritative answer:
Name:    st2.zoom.us
Address: 18.161.97.86
Name:    st2.zoom.us
Address: 18.161.97.64
Name:    st2.zoom.us
Address: 18.161.97.95

and later with:

Non-authoritative answer:
Name: st2.zoom.us
Address: 52.84.45.123
Name: st2.zoom.us
Address: 52.84.45.116
Name: st2.zoom.us
Address: 52.84.45.124
Name: st2.zoom.us
Address: 52.84.45.82
Name:    st2.zoom.us

what's wrong ? we refreshed url, we circumvent proxy, we retrieve it from external server, even from home...

is it the good url to retrieve IPRange for Zoom ?

Thanks for any help
