Using AWS IPs with AI platforms

All AWS addresses are datacenter IPs, and IP Judge labels them as such. ChatGPT and Claude don’t reject datacenter IPs outright, but an IP shared by many users, or listed as a proxy / VPN, runs into CAPTCHAs, phone verification and risk prompts more often.

Availability follows the location the platform sees for your IP. The region in the official list usually matches geolocation databases, but newly assigned ranges can take weeks to update. After launching a server, run the check on the home page to see the exit and region ChatGPT and Claude actually see. Scoring rules are on Method.
