Domain IP Lookup — Free Online Tool
Instant domain-to-IP resolution with IPv4 and IPv6.
Enter a domain above to see its IPv4 (A) and IPv6 (AAAA) addresses. Many domains have multiple A records for load balancing.
How to Use the Domain IP Lookup
The domain ip lookup is engineered for speed — most users get to a clean answer in under ten seconds. Here's the three-step workflow:
-
Step 1
Enter a domain (e.g.
github.com). Protocol and path are stripped automatically. -
Step 2
Click Lookup IP. We query DNS for both IPv4 (A records) and IPv6 (AAAA records).
-
Step 3
Review the results — multiple IPs per domain usually means load balancing or a CDN.
Benefits of Using Our Domain IP Lookup
Not every online web tools tool respects your time. This one does. Here's what you get when you choose BizNY:
- Returns both IPv4 and IPv6 in a single query.
- Shows all IPs returned — useful for understanding a CDN or load-balanced configuration.
- One-click copy of each IP address.
- Runs on our server, bypassing any browser CORS restrictions.
- No authentication, no rate-limiting on normal use.
- Fast — typically under 500 ms end-to-end.
The Growing Popularity of the Domain IP Lookup
Domain-to-IP lookup is a fundamental utility for anyone who troubleshoots web infrastructure. Common uses: confirming a site's server IP for firewall rules, diagnosing DNS propagation after a migration, verifying a CDN is active (multiple IPs across geographies), and investigating whether two domains share a host. Recent growth in traffic reflects the ongoing rise of US small-business web infrastructure complexity — more teams running custom domains on marketing platforms, cloud providers, and CDNs, and more need to understand where those domains actually point.
Who uses the domain ip lookup?
- SysAdmins configuring firewall rules by IP
- Developers verifying DNS after a hosting change
- SEO researchers detecting shared hosting
- Support engineers debugging connectivity issues
Frequently Asked Questions
Common questions about the domain ip lookup — if you have something else, drop us an email at support@bizny.co.
Why do some domains return multiple IPs?
Load balancing and CDNs. Major sites (google.com, github.com) use DNS round-robin or geo-routing, so queries from different locations — or at different times — can return different IPs.
What if a domain only has IPv4 and no IPv6?
That's still the norm for most US domains. IPv6 adoption has been slow; many hosting providers don't enable it by default.
Can I use this to find a private IP?
Only public IPs are returned, because DNS queries resolve from public DNS servers.
Does this reveal a server's physical location?
The IP itself can be reverse-looked up to an approximate region (via GeoIP databases), but that's a separate step. This tool just returns the IP.
How does this differ from DNS Lookup?
Our DNS Lookup returns all record types (A, AAAA, MX, NS, TXT, CNAME, SOA). This tool narrows the output to just the IPs.
