What does your IP address reveal?
Understand public and private IP addresses, approximate location and VPNs.
Public and private IP addresses are different
Your phone and computer can have different private addresses while sharing a public IPv4 address. Your router uses NAT to keep their connections separate. Astrotor shows the public address used by your request. IPv6 networks may use a different addressing arrangement.
Why does your IP show another city?
IP geolocation is not GPS. It estimates a region using network registrations and provider data. Mobile carriers, business networks and VPN exits can make another city appear. This alone does not indicate a connection problem, and an IP card does not reveal your exact street address.
What changes with a VPN?
A website will usually see your VPN server’s exit address. Comparing your address before and after connecting tells you whether that exit changed. This does not prove all traffic is protected; DNS routing and application behavior need separate checks. Astrotor does not infer definitive VPN usage from an IP or ASN.
How should you read the results?
Read the public IP as your connection’s exit, the ASN as the network announcing that address, and the city as an estimate. Refresh after switching between a VPN or mobile data to compare. The local development address 203.0.113.42 is a documentation example, not a real visitor address.
