IP Lookup
Inspect IP addresses for version, scope, and reverse DNS pointer.
Your IP Lookup
Validate IP format and understand its characteristics.
The IP Lookup tool quickly reveals whether an address is public or private, its version, scope, and reverse DNS details. Use it to validate network setups, troubleshoot connectivity, and document endpoint behaviors.
How it works
- Detects IP version — Automatically identifies IPv4 vs IPv6.
- Scope and reachability — Flags private vs public and global accessibility.
- Reverse DNS — Attempts PTR lookup for hostnames where available.
- Location hint — Shows ISP and rough location when available.
Examples
- 8.8.8.8 — Public IPv4 (Google DNS), global reachable.
- 2001:4860:4860::8888 — Public IPv6 (Google DNS).
- 10.0.0.5 — Private IPv4 inside corporate/home networks.
FAQ
- Why is my IP private? — Addresses like 10.x.x.x or 192.168.x.x are reserved for local networks.
- What is reverse PTR? — It maps an IP to a hostname if configured by the provider.
- How accurate is location? — Location is approximate and depends on ISP records.
- Does this test open ports? — No. It only inspects IP metadata and DNS.
