Hello razshai,

Thanks for choosing the Apple Support Communities. It sounds like you may have iCloud Private Relay turned on which may result in not seeing your IP on these pages. To turn that on and off, please follow the steps below.

About iCloud Private Relay - Apple Support

1. "Open the Settings app, then tap your name.
2. Tap iCloud, then select Private Relay. 
3. To turn Private Relay on or off, tap Private Relay.
4. To choose a setting for your IP address, tap IP Address Location.

• To let sites show you localized content in Safari while your IP address stays hidden, tap Maintain general location.
• To use a broader location for your IP address, still within your country and time zone, tap Use country and time zone."

We hope this helps.

Cheers!
