"Temporarily allow a website to see your IP address in Safari on Mac"
"If a website relies on IP filtering, monitoring or rate-limiting, it might require your IP address to be visible. You can turn off iCloud Private Relay temporarily for that website only.
In the Safari app on your Mac, choose View > Reload and Show IP Address.
Your IP address remains visible to that website until you leave the website or close its Safari tab. iCloud Private Relay remains on for other websites and Safari tabs." https://support.apple.com/guide/safari/ibrwc3feb013/
