Tool guide
What does this tool do?
The IP Lookup tool shows the public address visible from this browser or inspects an IPv4 or IPv6 address you enter. Use it to confirm the address seen by external services, then review approximate network, ISP, ASN and location context. The result is best treated as routing metadata: it can explain which provider or gateway is involved, but it should not be used as a precise physical location or personal identity.
How to use
- Leave the field blank to detect your current public IP address.
- Enter an IPv4 or IPv6 address to inspect a specific address.
- Review the network, ASN and approximate location fields.
- Open RDAP or Reverse DNS when you need registration or PTR context.
When to use
- Allowlisting an office, home or VPN connection.
- Checking whether a VPN or proxy changed your visible address.
- Investigating an IP address from logs or abuse reports.
How it works
NexKit sends the lookup value to a public IP metadata endpoint and displays the normalized response. Network ownership and location can be approximate because ISPs, mobile carriers, VPNs and cloud providers route traffic through shared infrastructure.

FAQ
Can this tool show an exact address?
No. IP location is approximate and can reflect a provider gateway, VPN exit or routing region.
Built for quick answers
Clean results without dashboards, accounts or unnecessary steps.
Lightweight by design
Local calculation and public standards keep infrastructure costs low.
Privacy-respecting
NexKit does not create a searchable history of your network queries. Cloudflare Web Analytics measures aggregate visits and performance.
Know what you are checking
A complete toolkit for everyday network troubleshooting.
Check connectivity and identity, verify DNS and registration data, review certificates and response headers, then calculate IPv4 network ranges—all from one focused workspace.
Transparent by design
Know where every result comes from.
NexKit combines local browser calculations with public, standards-based network services. No account or NexKit query history is created.
DNS + Reverse DNS
Resolved through an encrypted public DNS-over-HTTPS request.
RDAP + Certificates
Read from authoritative registry routes and public certificate logs.
IP + IPv6 + Headers
Checked through focused public endpoints; providers may apply rate limits.
Common questions
Useful context before you act on a result.
Does NexKit store my network queries?
NexKit does not create an account or searchable query history. Tools that use public endpoints still send the minimum lookup value to the named service that produces the result.
What is the difference between DNS and reverse DNS?
DNS normally maps a hostname to records such as IP addresses. Reverse DNS maps an IP address back to an optional PTR hostname.
Is RDAP the same as WHOIS?
RDAP provides similar registration data through structured HTTPS responses. Available fields and redaction vary by registry.
Does the SSL checker connect to the live server?
It reads the newest matching public Certificate Transparency record. Use it for certificate identity and lifecycle checks, not as proof of the server's current TLS configuration.
