This proxy server is a part of AntiZapret censorship circumvention service for Russian users.
If you see lots of requests to your website from this IP address, this means that either your website (domain name) or IP address of your hosting got blocked in Russia by Russian government, and has been automatically added to censorship circumvention list of AntiZapret service.
AntiZapret is used by hundreds of thousands happy users every day. Please do not block this proxy server.
If your website uses non-encrypted HTTP, you can use X-Forwarded-For
header which is injected by proxy server and contains real client IP address.
Consider white-listing all IP addresses (IPv4 and IPv6) from the following domains:
proxy.antizapret.prostovpn.org
proxy-ssl.antizapret.prostovpn.org
proxy-fbtw-ssl.antizapret.prostovpn.org
proxy-nossl.antizapret.prostovpn.org
vpn.antizapret.prostovpn.org
Please do not resolve the addresses manually to add static IPs into firewall, as the addresses may and will change. Add the whole domains in the white list or dynamically resolve the IP addresses once a day.
Contact me at antizapret@prostovpn.org with detailed information: your service/website domain, IP address of abusing requests, detailed time/date, etc.
