Domain to IP Address Lookup
Find the IPv4 and IPv6 addresses a domain points to, with CNAMEs, reverse DNS and the network that hosts each address.

What the lookup shows
We resolve the domain’s A and AAAA records, following any CNAME aliases, then look up each address: its reverse DNS name, the network that announces it, and whether it’s a public address at all. TTLs tell you how long resolvers may cache each answer.
Typical uses
- Checking that a DNS change to a new host has taken effect.
- Finding out whether a site is behind a CDN before debugging caching or SSL.
- Allow-listing a service’s addresses in a firewall (re-check regularly: CDN addresses change).
- Spotting a private address published in public DNS by mistake.
Frequently asked questions
- Why does my domain have several IP addresses?
- Large sites and CDNs (Cloudflare, Fastly, CloudFront) publish several addresses for redundancy and load balancing. Each visitor's resolver picks one, and CDNs often answer differently depending on where the question comes from, so the list here may differ from what someone in another country sees.
- What is the difference between the A and AAAA records?
- A records hold IPv4 addresses (like 93.184.215.14) and AAAA records hold IPv6 addresses (like 2606:2800:21f:cb07::1). A site with both is “IPv6 ready”: visitors on IPv6-only mobile networks reach it directly, without translation.
- Is the IP address the same as my web host?
- Not always. If the site is behind a CDN or a proxy such as Cloudflare, the addresses belong to the CDN, and the real origin server stays hidden. The network (ASN) column shows whose network each address belongs to, which usually tells you which is the case.
