When performing a 'cloudflare ip address check,' why might I see different IP addresses for the same domain over time or from different locations?

Cloudflare utilizes a vast global network of data centers (Points of Presence, or PoPs). When you perform an IP address check, your DNS query is typically directed to the nearest or most optimal Cloudflare PoP based on your geographical location. Cloudflare dynamically routes traffic, balances load across its network, and makes performance optimizations, which means that the specific Cloudflare IP address returned for a domain can vary depending on your location, your ISP's routing, and Cloudflare's internal network state at any given moment.
