What is an IP Lookup / Geolocation tool?
An IP address (Internet Protocol) is the numerical identifier assigned to every device connected to the internet. Behind this string of numbers lie concrete pieces of information: the country and city the connection is coming from, the internet service provider, the organisation that owns the address range, and even the type of connection in use.
Twaino’s IP Lookup / Geolocation tool queries any IP address and returns all of this data in just a few seconds — with no installation, no account and no usage limit. Ideal for SEO professionals, developers and anyone looking to understand the origin of traffic or qualify a visit source.

How to use the IP Lookup
Paste the IPv4 or IPv6 address you want to analyse into the dedicated field.
The tool queries geolocation databases and internet registries in real time.
The country, city, internet service provider, organisation and connection type are displayed instantly.
How does IP geolocation work?
Each IP address is assigned by bodies called RIRs (Regional Internet Registries) to specific internet service providers or organisations. These allocations are public and regularly updated in global databases. The tool cross-references several sources to provide a reliable result:
- The WHOIS databases of regional registries (RIPE, ARIN, APNIC…) which indicate which organisation owns the address range.
- The IP geolocation databases which map each block of addresses to a geographic area (country, region, city).
- The BGP data (Border Gateway Protocol) which provides information about the autonomous network (ASN) declared by the access provider.
- The connection-type classification: residential, mobile, business, hosting or private network (VPN).
Accuracy is highest at the country level and very good at the city level for standard residential connections.
💡 Our tip
If the displayed city does not match what you expected, do not conclude that there is an error: an access provider may centralise its connections in a city different from that of the end user. Location at the country level, on the other hand, remains very reliable in the vast majority of cases.
Why run an IP Lookup?
Knowing the information associated with an IP address is useful in many professional contexts, from SEO to security and audience analysis:
| ✅ SEO & analytics side | 🛡️ Technical & security side |
|---|---|
| • Check the geographic origin of suspicious traffic • Qualify the location of backlinks • Understand localised search results • Check the IP of your own hosting server |
• Identify a bot or scraper • Detect the use of a VPN or proxy • Diagnose unusual access in your logs • Verify the consistency of a contact source |
In SEO, the geographic origin of an IP is especially useful for analysing an inbound link profile as part of a full SEO audit or for understanding why content ranks differently across countries.

Concrete use cases for SEO professionals
Beyond simple curiosity, the IP Lookup fits naturally into several SEO and marketing workflows:
- Server log analysis: identify the geographic origin and connection type of your most active visitors to distinguish real users from indexing bots.
- Link-building audit: check that backlinks supposedly coming from French, German or American sites really correspond to servers hosted in those areas.
- Geographic targeting: make sure your server’s IP is properly tied to the right country when operating a site with a local audience — a point directly linked to the geographic signals Google takes into account.
- Competitive intelligence: learn the host and organisation associated with a competitor site’s IP to infer its technical infrastructure.
To go further in the technical analysis of a site, combine this tool with the on-page SEO audit or explore all the resources available in the Twaino free tools suite.

Twaino’s IP Lookup / Geolocation tool reveals in seconds the country, city, ISP, organisation and connection type associated with any IP address. A simple yet valuable tool for traffic analysis, link auditing and technical diagnostics.
Frequently asked questions
Is the IP Lookup tool free?
Yes, the tool is entirely free. There is no sign-up required and no limit on the number of searches. It is part of the suite of free SEO tools offered by Twaino, accessible directly online with no installation.
How accurate is IP geolocation?
Accuracy is excellent at the country level, with a reliability rate above 95% for most public IP addresses. At the city level, accuracy is good for standard residential connections, but may vary if the access provider centralises its connections in a city different from that of the real user.
Can an IPv6 address be geolocated?
Yes, the tool supports both IPv4 and IPv6 addresses. Geolocation databases now cover both protocols, even if the coverage of IPv6 blocks may be slightly less granular than that of historical IPv4 blocks.
Why does the displayed location not match the user’s real city?
Several reasons can explain this gap: the use of a VPN or proxy that masks the real location, an access provider that routes its connections through a centralised node in another city, or an IP address belonging to a corporate network whose head office is registered in a different area. The connection type displayed by the tool helps identify these cases.
What is the difference between the organisation and the access provider displayed?
The internet service provider (ISP) is the operator that supplies the connection to the end user (Orange, SFR, OVH…). The organisation is the entity to which the IP address range is officially assigned in the WHOIS registries: it may be the same operator, but it may also be a company that leases blocks of addresses from a host or another ISP. This distinction is useful for identifying whether an IP belongs to a cloud host, a corporate network or an individual subscriber.
