IP Information

Key Takeaways

• IP geolocation hits 99.8% accuracy at country level, but city-level accuracy is much weaker — MaxMind estimates around 66% accuracy within 50 km for U.S. IPs (MaxMind).
• On March 28, 2026, Google’s IPv6 stats passed 50.10% of internet traffic for the first time, meaning more than half of users accessing Google did so over IPv6 on that day. Many users now have both an IPv4 and an IPv6 address active at the same time on dual-stack networks.
• An IP address can reveal your network provider and approximate location, but a normal public IP lookup does not directly reveal your name, phone number, or street address.

What Is IP Information?

Every internet connection uses an IP address, usually assigned by an internet provider, hosting provider, mobile carrier, VPN, or organization. When your browser or app connects to a website, the server can see the public source IP address used for that connection. From that IP, lookup databases can often estimate network metadata such as country, region, city, ISP or organization, ASN, hostname, coordinates, and timezone.

The ITU estimated that roughly 6 billion people were online in 2025, equal to about three-quarters of the world’s population (ITU, Nov 2025). Each internet connection leaves behind basic network-level information, although location results are approximate and depend on the quality of the IP geolocation database.

This tool reads publicly available IP metadata and presents it clearly. Enter any IP address and you can see the city, region, country, ISP, ASN, hostname, coordinates, and timezone when available — all in seconds, for free. It works with both IPv4 and IPv6 addresses.

Every active internet connection exposes a public source IP address to the server it connects to. That IP can often be matched to approximate location, network provider, and autonomous system data using geolocation and routing databases, but it should not be treated as a precise home address or personal identity lookup (ITU, 2025).

What Data Does an IP Lookup Reveal?

An IP lookup can return several useful network data points, depending on the database and the IP address being checked. The most important is geolocation: MaxMind estimates that modern GeoIP databases identify an IP's country with about 99.8% accuracy, while U.S. city-level accuracy is much lower — around 66% within a 50 km radius (MaxMind). Here's what you can get from each lookup:

• Geographic Location — City, region, postal code, and country associated with the IP address, when available.
• Coordinates — Approximate latitude and longitude associated with the IP/network, not your front door.
• ISP & Organization — The ISP, hosting provider, mobile carrier, VPN, or organization using that IP range.
• ASN (Autonomous System Number) — A unique ID for the network operator controlling or announcing that IP range.
• Hostname — The readable reverse DNS name tied to the IP, such as dns.google, when available.
• Timezone — The estimated timezone for the IP’s approximate location, useful for server and log verification.
• Continent — Continent name and code, such as NA, EU, or AS.

MaxMind's GeoIP products identify an IP's country with about 99.8% accuracy. For IPs located within the U.S., MaxMind estimates around 80% accuracy at the state/region level and around 66% city-level accuracy within a 50 km radius. Accuracy varies by country, ISP infrastructure, mobile networks, VPN usage, and how IP ranges are routed or reassigned (MaxMind).

When Should You Use an IP Checker?

IP lookups serve a wider range of tasks than most people expect. In 2025, 32% of U.S. adults used a VPN, according to Security.org's consumer survey (Security.org, 2025). Because VPNs, proxies, mobile networks, and cloud providers can change the public IP address a website sees, IP verification is useful for access control, fraud checks, troubleshooting, and content delivery. Here are the most common scenarios:

1. Verify VPN Connectivity — Confirm your public IP location matches the VPN server you selected. If the lookup still shows your real ISP or normal location, your browser traffic may not be routing through the VPN correctly.
2. Security Audits — Spot an unfamiliar login in your account alerts? Look up the IP to estimate which network, ISP, ASN, and city the attempt came from. You can also check any suspicious shortened URLs as part of the same investigation.
3. Website Localization Testing — Developers use IP data to test region-specific content, pricing, language, and access rules. Verifying the lookup output helps confirm that geo-targeting logic works as intended.
4. Network Troubleshooting — Identify the ASN and ISP associated with a slow or unresponsive connection. The ASN can help you see which network operator, hosting provider, mobile carrier, or upstream route may need investigation. For related diagnostics, the SMTP connectivity checker can verify mail server reachability from an external test point.
5. Content Compliance — Streaming services, licensing deals, fraud controls, and regional regulations often require websites to estimate where traffic originates. An IP lookup gives you that data quickly, with no signup required.

Security.org's 2025 consumer survey found that 32% of U.S. adults used a VPN. The report lists privacy, security, safer public Wi-Fi use, reduced tracking, work requirements, and access to region-restricted media among common VPN reasons. IP verification tools help users and developers confirm the public IP address a website sees, but results should be treated as approximate because VPNs, proxies, mobile networks, and cloud providers can all affect IP location data (Security.org, 2025).

IPv4 Exhaustion and the IPv6 Shift

The internet's address supply changed permanently as the available IPv4 pool dried up across regional internet registries. RIPE NCC, the registry for Europe, the Middle East, and parts of Central Asia, exhausted its remaining IPv4 pool in November 2019 after making its final allocation from the last available addresses (RIPE NCC). IPv4 provides roughly 4.3 billion total addresses, which is not enough for today’s global internet, especially with smartphones, servers, cloud platforms, and connected devices all needing network access.

IPv6 was designed as the long-term successor to IPv4, with a much larger 128-bit address space. Adoption has continued to grow: on March 28, 2026, Google’s IPv6 measurements reached 50.10% for the first time, meaning more than half of Google access used IPv6 on that day (The Register, April 2026). This is an important milestone, but it does not mean IPv6 carried more than half of all global internet traffic across every measurement source.

Worth knowing: many modern networks use dual-stack or IPv6 with IPv4 compatibility, so your device or connection may have both IPv4 and IPv6 connectivity active at the same time.

RIPE NCC exhausted its remaining IPv4 pool in November 2019, marking another major step in the long-running IPv4 scarcity problem. Google’s IPv6 measurements later crossed 50.10% on March 28, 2026, showing that IPv6 adoption has reached majority usage for Google access, although other sources such as Cloudflare and APNIC were still below 50% at the time (The Register, April 2026).

Frequently Asked Questions

How accurate is IP geolocation?

IP geolocation can be very accurate at the country level. MaxMind estimates about 99.8% accuracy for country-level results in its GeoIP products. At more specific levels, accuracy drops: for U.S. IP addresses, MaxMind estimates around 80% accuracy at the state or region level and roughly 66% city-level accuracy within a 50 km radius. The location you see is an approximate area associated with the IP address or network — not your physical front door (MaxMind).

Does this tool show my name or street address?

No. A normal public IP lookup does not directly reveal your name, phone number, or exact street address. It usually shows network-level information such as ISP, organization, ASN, and approximate location. However, an ISP, mobile carrier, VPN provider, workplace, school, or website with account logs may be able to associate an IP address with a subscriber or user account when combined with additional records. Access to subscriber information depends on the provider, jurisdiction, and valid legal process.

What is an ASN?

An Autonomous System Number (ASN) is a unique identifier used in internet routing. It identifies an autonomous system: a group of IP networks operated by one or more network operators under a single, clearly defined routing policy. Google operates AS15169, for example. ASNs are assigned through regional internet registries such as RIPE NCC and ARIN, and they help identify which network announces a given IP range.

Why is my IP showing the wrong city?

IP geolocation is approximate. Your IP may show the wrong city because ISPs often assign addresses from centralized pools, route traffic through regional infrastructure, use mobile carrier gateways, or move IP ranges between regions. VPNs, proxies, hosting providers, and recently reassigned IP ranges can also confuse geolocation databases. This is one reason city-level IP accuracy is much lower than country-level accuracy, even in leading databases.

What's the difference between IPv4 and IPv6?

IPv4 uses a 32-bit format, such as 8.8.8.8, and supports roughly 4.3 billion total addresses. The global IANA IPv4 free pool was depleted in 2011, and RIPE NCC exhausted its remaining IPv4 pool in 2019. IPv6 uses a 128-bit format, such as 2001:4860:4860::8888, giving the internet a vastly larger address space. On March 28, 2026, Google’s IPv6 measurements reached 50.10% for the first time, meaning more than half of Google access used IPv6 on that day. If your connection supports both IPv4 and IPv6, this tool shows the public IP address your browser actually used to connect to the tool.
