I wanted to cover a quick topic here based on a few requests I have had for CRM Online. There are IP Address Ranges used by CRM Online that should not be blocked by a firewall, antivirus, or any other network appliance. These are below:

North America
157.55.131.0/25
65.55.114.64/26
65.55.123.32/27
65.55.183.192/26
64.4.19.0/24

Europe
157.55.230.0/25
157.55.44.224/27
94.245.112.224/27
94.245.120.0/27
157.56.115.0/24

Asia-Pacific
111.221.17.96/27
111.221.22.128/26
207.46.63.96/27
111.221.120.0/24

**Please note that these are IP Address ranges that are managed solely by CRM. There may be other IP Addresses used that are not mentioned here.

Below is a link to the KB article that describes this as well.
