IP Address Lookup
Find the location, internet provider (ISP), ASN, and time zone of any IPv4 or IPv6 address or domain name. Check your own public IP in one click.
Free Online IP Address Lookup Tool
An IP address lookup tells you where an internet address is registered and who runs the network behind it. Paste any IPv4 or IPv6 address, or just a domain name, and the OffSecPath IP Lookup returns the country, region, city, time zone, internet service provider, organization, and autonomous system number (ASN) in a few seconds. It is a quick first step when you are checking a suspicious login, reading an email header, troubleshooting a connection, or simply curious where a server is hosted.
How to Use the IP Lookup
- Type or paste an IP address (for example
8.8.8.8) or a domain name (for exampleexample.com) into the box. - Press Lookup or hit Enter. For a domain, the tool first finds its IP address, then looks that address up.
- Read the summary cards at the top and the full details in the results panel.
- Use Copy Results to save the details, or open the map link to see the approximate location.
- Press Detect My IP to see the public address your connection is using right now.
What Information Does an IP Lookup Show?
| Field | What it means |
|---|---|
| IP address & version | The address that was looked up and whether it is IPv4 or IPv6. |
| Country, region, city | The approximate place where the address is used, taken from geolocation databases. |
| Postal code & coordinates | A rough map point. It usually marks the middle of an area, not a street address. |
| Time zone | The local time zone for the estimated location. |
| ISP & organization | The company that provides or owns the connection, such as an internet provider or hosting company. |
| ASN | The autonomous system number, which identifies the network that announces the address on the internet. |
IPv4 and IPv6: What Is the Difference?
IPv4 addresses have four numbers separated by dots, such as 203.0.113.25. There are only about 4.3 billion of them, and they are now in short supply. IPv6 was created to fix this. An IPv6 address uses eight groups of hexadecimal characters separated by colons, such as 2001:4860:4860::8888, and provides a practically unlimited number of addresses. This tool accepts both, including shortened IPv6 forms that use ::.
How Accurate Is IP Geolocation?
IP geolocation is an estimate, not a precise position. Country-level results are usually reliable. City-level results are less certain and are often wrong by tens of kilometres, especially on mobile networks. A few things can make the result differ from the real location:
- VPNs and proxies show the location of the VPN server, not the user.
- Mobile and satellite networks often route traffic through a central point far from the device.
- Shared addresses (carrier-grade NAT) can serve thousands of customers at once.
- Outdated databases may still list an address under its previous owner.
An IP lookup cannot reveal a person’s name, street address, or identity. It shows the network the address belongs to.
Common Uses for an IP Lookup
- Security checks: see where a failed or unfamiliar login attempt came from.
- Email headers: check the origin of a suspicious message or spam.
- Troubleshooting: confirm which provider or data centre a server is in.
- VPN testing: verify that your public IP and location changed after connecting.
- Web administration: investigate odd traffic in your server logs.
Private and Reserved IP Addresses
Some addresses are not public and have no location. These include private ranges used inside home and office networks (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16), loopback addresses such as 127.0.0.1, link-local addresses (169.254.0.0/16 and fe80::/10), and multicast ranges. If you enter one of these, the tool explains what it is instead of sending a lookup.
Privacy: What Happens When You Look Up an IP
This page runs in your browser and does not store your lookups. To get the data, your browser sends the IP address you entered to a public IP geolocation service (ipwho.is, with ipapi.co and ipinfo.io as backups). When you enter a domain name, it is resolved through Google Public DNS. Those services receive the address or domain you look up, and your own IP address as part of the normal web request, and they have their own privacy policies. Do not look up anything you are not comfortable sharing with them.
Frequently Asked Questions (FAQ)
Can I find someone’s exact home address from an IP address?
No. IP geolocation only gives an approximate area, usually the city or region of the internet provider’s network. It does not identify a person or a street address.
Why is the location different from where I really am?
Geolocation databases are estimates. A VPN, a mobile network, a corporate network, or an outdated database entry can all place an address in the wrong city or even the wrong country.
Can I look up a domain name instead of an IP address?
Yes. Enter a domain such as example.com and the tool finds its IP address first, then shows the details for that address. A domain can have several IPs, so the first one found is used.
Does the IP Lookup support IPv6?
Yes. Both IPv4 and IPv6 addresses work, including shortened IPv6 forms.
What is an ASN?
An autonomous system number identifies a large network on the internet, such as an ISP, a cloud provider, or a university. It helps show who is responsible for an IP address range.
Why do I see a “lookup failed” or rate limit message?
The free geolocation services used by this tool limit how many requests they accept per day. If one is busy the tool tries a backup. If every service is limited, wait a while and try again.
Is this IP lookup free?
Yes. There is no sign-up and no fee.
