About IP and connections
What is an IP address?
The meaning and limitations of the source IP address visible to a website.
Updated: October 9, 2026
An IP address identifies a network endpoint. Different values in device settings and an IP-checking website are not necessarily a fault: a local address and the address visible on the internet can differ.
Local address versus internet-facing address
For example, 192.168.1.10 is a private address used inside a home or organization, not a globally unique device number. Address translation or a corporate gateway can expose an exit address instead. An IPv6 device can also have several addresses; observing one does not enumerate them all.
Check your IP with NetKarte
- Read the IP at the top of Network diagnostics.
- Check IPv4/IPv6 and the source header.
- Read ASN and network operator for network affiliation.
- Use IP Information Lookup to investigate an arbitrary address's registration range.
The displayed IP is the source selected for this request from trusted managed-proxy information, not a scan of your device's interfaces.
When the result is unexpected
Check VPN, corporate gateway, and mobile-network settings or ask your administrator. If comparing another permitted connection, run diagnostics again and note the connection conditions. Do not disable organizational protections without permission.
An IP alone cannot establish a person's identity, exact address, or connection safety. Failure to retrieve an IP also does not mean no address exists.
