I have a problem with some IP addresses(in SAME ISP) that trying to access my website (Azure VM - windows server 2012 - IIS8).
for example this IP address 5.29.99.2 or this 3.7.142.100.100 cannot access to my website.
for other users with different IP
address and
different ISP all works fine.
note that I did't defined any firewall restrictions manually.
What is the problem?
thanks for your help!
