Frequently asked questions
Is IP Address Checker free?
Yes. ToolNest provides IP Address Checker as a free browser-based utility.
Does IP Address Checker require an account?
No account is required. Open the tool and use it directly in your browser.
Can IP Address Checker check both IPv4 and IPv6 addresses?
Yes. Paste an IPv4 or IPv6 address, tap Inspect IP, and the tool returns a copy-ready report. IPv4 reports include class, range, private or public hints, integer, hex, binary octets, reverse DNS pointer, and a /24 subnet hint. IPv6 reports include compact form and common range categories.
Does IP Address Checker show private IP address ranges?
Yes. It flags common IPv4 private ranges such as 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, plus loopback, link-local, multicast, carrier-grade NAT, reserved, and documentation ranges.
Does IP Address Checker reveal who owns an IP address?
No. It is a browser-side address inspector for format and range hints. It does not perform live geolocation, ISP ownership, or abuse-database lookup. Use authoritative network or registry sources for ownership decisions.
