Common questions about 23.251.121.236
Is this someone's exact address?
No. IP geolocation resolves to the area where the block is registered by Zenlayer Inc, and can be off by tens of kilometres, or point to a different city entirely for mobile and satellite connections. It is not a street address and should not be treated as one.
Why does 23.251.121.236 show San Jose, California, United States when I'm somewhere else?
Because the location belongs to the network, not to you. If you're on a VPN, a corporate connection or a mobile carrier that routes traffic through a central gateway, the address reflects that gateway.
Can I change it?
Your provider assigns it, so you can't pick it directly. Restarting your router often gets you a new one if your ISP uses dynamic addresses. To control which address websites see, route your traffic through a VPN.
