Every public website name is mapped in DNS. An A record returns one or more IPv4 addresses; an AAAA record returns IPv6. Those addresses are what browsers connect to (or what a CDN terminates before forwarding to an origin).
PINIP’s Domain to IP tool resolves A, AAAA, MX, NS, TXT, and CNAME so you can see the server side of a hostname in one place.
If a site sits behind Cloudflare, Fastly, Akamai, or a cloud load balancer, the A/AAAA you see is often the edge, not the origin server in the customer’s VPC. That is expected: reverse IP on a CDN anycast address will show many unrelated hostnames.
Tips:
- Check historical DNS or mail records when you need the origin.
- Compare multiple record types — MX sometimes points closer to the operator’s infrastructure.
- After you have an IP, open the full IP Lookup and Domains on IP reports.
