You do not have permission to edit this page, for the following reason:
This IP address has been blocked from editing Wikipedia.This does not affect your ability to read Wikipedia pages.
The IP address or range 202.165.120.0/22 has been blocked by ?ST47? for the following reason(s):
These types of services are commonly used for abusive editing and circumventing Wikipedia policies, so Wikipedia blocks them as a preventive measure — even if you personally haven't done anything wrong.
How to fix it:
- Turn off VPNs, proxies, or tools like iCloud Private Relay (for Apple users) or Microsoft Edge Secure Network. This is the most frequent reason users encounter this block.
- Try a different connection. Switch between Wi-Fi and mobile data, or use a home network instead of a public or work one.
- Whitelist Wikipedia. You may be able to whitelist Wikipedia from your VPN so that connections to Wikipedia aren't through a VPN service. Instructions for whitelisting Wikipedia on iCloud Private Relay can be found here.
- Still blocked? If you believe you are not running an anonymizing proxy or Tor, you should consider checking the configuration to make sure it is accurate. Sometimes the configuration for your network is changed without your knowledge, sometimes by malware. In truly exceptional circumstances, you may request IP block exemption. Approval is limited and based on specific criteria, and you should only request it if you have no other way to edit Wikipedia.
Note: These blocks are about the type of internet connection, not your actions. We appreciate good-faith contributors and want to help you get editing again.
