How does a domain name become an IP address?

When you look up a domain, DNS resolvers read its A record (IPv4) and AAAA record (IPv6). Those records are what browsers actually connect to — the domain name is just the human-friendly handle for them.

Can one domain have several IP addresses?

Yes — large sites publish multiple A and AAAA records so traffic can be spread across several servers or points of presence. Your browser picks one (or falls back to another if the first fails).

Why does the IP I see change over time?

Websites move between servers, use load balancers or sit behind CDNs whose addresses vary by region and moment. If the domain's DNS changes, the IP you resolve today may not be the one you resolve tomorrow.
