Who can see your IP address?
ISP, the site you visit, the café, and any VPN you chose. Not the whole internet by default.
Who can see your IP address? Short list: your ISP, the site or app you connected to, anyone on the same local network who can watch packets, and any middlebox you chose (VPN, proxy, corporate gateway). Search engines do not get a live feed of your IP just because you exist. Random people on a forum do not, unless you posted it or a log leaked. Knowing the list is how you decide whether to hide your IP, change networks, or just stop oversharing.
The ISP and the local path
The ISP assigned the public IP. They can map it to an account on their side. On café WiFi, the hotspot operator can see that your device is talking, and often which destinations, unless you use a VPN. HTTPS still hides page contents. It does not hide that a connection happened.
Roommates on your LAN do not automatically see your public IP in a dashboard, but they share it. The router’s admin page does.
The destination
Every web server logs the source IP unless it is configured not to. CDNs, analytics, and fraud tools store IP location (country, sometimes city) next to the visit. An IP lookup of that log line shows the ISP, not your name.
If you are logged in, the site already has a stronger ID than the IP. Hiding the IP then is about the next session and about the café, not about erasing the account.
Middlemen you installed
A VPN provider sees your real IP on the way in and presents theirs on the way out. A proxy the same, often with less encryption. Corporate devices may force traffic through a gateway; then work sees everything and the internet sees the office IP.
Browser extensions that “protect privacy” can also read the IP and the URL. Keep that list short.
What to do with this map
- For public WiFi, assume the hotspot is nosy; use a VPN and confirm the new public IP.
- For websites, assume they log IP plus time; use unique passwords and 2FA anyway.
- For strangers, do not paste your IP in screenshots of “what is my IP” tools.
- For geolocation ads, a VPN changes the country guess; it does not delete cookies.
Your IP is a network name, not a confession. The people who see it are the ones on the path. Shorten the path you do not trust, and check the number so you know whose path you are on.
