IP Compare

IP Compare lets you place two IP addresses side by side to instantly see how they differ in location, network, distance, and more. Whether you are verifying that your VPN is working, troubleshooting CDN routing, or simply curious about the geographic distance between two endpoints, this tool provides a clear, visual comparison on an interactive map.

Why Compare Two IP Addresses?

A single IP lookup tells you about one address. Comparing two IPs reveals the relationship between them. This is useful for geolocation verification — confirming that an IP resolves to the location you expect — and for network troubleshooting, where understanding the difference between two endpoints helps diagnose routing, performance, or configuration issues.

One of the most common use cases is VPN verification. By comparing your real IP address with the one reported while connected to a VPN, you can confirm that your traffic is actually being routed through the VPN server and that your true location is not being leaked. Learn more about this in our guide on how to check if your VPN is working.

What the Comparison Shows

When you compare two IPs, the tool displays a detailed breakdown for each address, including:

• Geographic location — Country, region, city, and approximate coordinates plotted on a map.
• ISP and organization — The internet service provider or hosting company operating the IP.
• ASN (Autonomous System Number) — The network identifier that tells you which organization controls the routing for that IP block.
• Distance — The geographic distance between the two IP locations, calculated from their coordinates.
• IP type — Whether each address is residential, datacenter, VPN, or a known proxy.

These details are presented side by side, making differences immediately obvious. Both addresses are also plotted on a map with a line showing the distance between them.

IPv4 vs IPv6 Comparison

IP Compare works with both IPv4 and IPv6 addresses, and you can mix them freely. This is particularly useful when checking whether your IPv4 and IPv6 addresses resolve to the same location, which is important for verifying that dual-stack configurations are consistent. As IPv6 adoption continues to grow — currently around 40% of global traffic according to Google’s IPv6 statistics — being able to compare both protocol versions becomes increasingly relevant.

Common Use Cases

IP Compare is helpful in a variety of real-world scenarios:

• Verifying VPN connections — Compare your IP before and after connecting to a VPN. If the locations match, the VPN is not routing your traffic correctly. If they differ and the VPN IP shows the expected server location, everything is working as intended.
• Checking CDN routing — Compare the IP of a CDN edge node with your own IP to verify that the CDN is serving content from a geographically close location. Large distances may explain latency issues.
• Comparing home vs office networks — See how your home and office connections differ in terms of ISP, network type, and geographic location.
• Investigating suspicious activity — If you see logins from two different IPs, comparing them can reveal whether they are from the same network or entirely different regions.

Understanding the Results

When reviewing a comparison, pay attention to a few key indicators. A short distance between two IPs with different ASNs typically means the addresses are in the same city but on different networks — common when comparing a residential connection with a mobile carrier. A large distance with the same ASN can indicate a distributed network like a cloud provider or CDN operating in multiple regions.

If one IP shows as a datacenter or VPN while the other is residential, this is expected when comparing a VPN-connected address with a direct connection. For a deeper look at any individual IP, use the full IP Lookup tool to see complete geolocation and enrichment data.

How IP Geolocation Works

The location data behind IP Compare comes from geolocation databases that map IP address ranges to geographic coordinates. These databases are compiled from regional internet registries (RIRs), ISP data, and network measurements. Accuracy varies — city-level precision is typical for residential IPs, while datacenter and VPN addresses may geolocate to the provider’s registered address rather than the physical server location.
