Free network, IP and DNS lookup tools
Find your IP address, then ping a host, see who an IP is registered to, or inspect a domain's DNS records. No registration needed.

Detecting your IP address…
Your IP address could not be determined right now.
This is a private address, so you are probably on a local or development network. Public lookups are not available for it.

What is my IP address?
Your IP address is the public address your internet connection uses to talk to websites. It is assigned by your internet provider, so everyone on the same home or office network usually shares one, and it can change over time. NetInspect shows the address your connection presents to us (IPv4 or IPv6). A VPN or proxy changes the address you see here to the one of the VPN or proxy server.
What is Ping?
Ping sends small test messages (ICMP echo requests) to a host and measures how long the answers take. It tells you whether a server is reachable from the internet, how many of the messages were lost, and the minimum, average and maximum round-trip time in milliseconds. High delay or packet loss points to network problems between you and the host.
What is an IP WHOIS lookup?
An IP WHOIS lookup shows who an IP address block is registered to: the organization, the network range, the country, the regional internet registry that manages it, the autonomous system number (ASN) that announces it, and an abuse contact. It is useful to find out who runs a server or where to report abuse.
What are DNS records?
DNS records tell the internet where a domain lives and how it is used. An A record maps the name to an IPv4 address and an AAAA record to an IPv6 address. MX records name the mail servers, NS records the authoritative name servers, CNAME records point a name to another name, and TXT records hold free text such as email authentication (SPF) and domain verification entries. The TTL is how many seconds a record may be cached.
Frequently asked questions
- Is NetInspect free?
- Yes. All tools are free to use and need no registration or account.
- Why is the IP address shown for me different from my device's address?
- Devices in a home or office network have private addresses (like 192.168.1.20). NetInspect shows the public address of your connection, which is the one websites see. A VPN or proxy replaces it with its own.
- Why does ping say a website is not reachable when it works in my browser?
- Many servers and firewalls ignore or block ping (ICMP echo) requests while still serving web pages. "Not reachable" here means the host did not answer ping, not that the website is down.
- Can I check a private address like 192.168.1.1 or localhost?
- No. NetInspect only checks public internet addresses. Private, loopback and other internal addresses and names are refused for safety, because the checks run from our servers and not from your network.
- Where does the IP WHOIS information come from?
- From the regional internet registries (ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC) through their RDAP services, the structured successor of the WHOIS protocol. The ASN comes from public routing data.
- Which DNS record types can I look up?
- A, AAAA, MX, NS, TXT and CNAME. Results come from public recursive resolvers, so they show what the internet sees, including caching delays after a change.
- Does NetInspect store my lookups?
- No lookup history is kept. Server logs contain only shortened IP addresses and are deleted after 30 days. See the About page for details.
