How do I find my IP address on my iMac?

I have been using the google chrome browser. I had this happen before where I could not sign in to Michael's and they helped me and I was on for a short time and it did it again. I changed my password. I went to Safari and tried again on there and could not connect. I am on WiFi and this is my iMac. I don't have the app for them on anything. I prefer doing things on my computer... even though I have an ipad and an Apple phone.

iMac 27″, macOS 15.3

The IP Address viewed on a website is the IP Address of your router, not your Mac. All devices that you use on your WiFi are going to broadcast the exact same IP Address. Your Mac does have a unique private IP address that is assigned by your router, but it is not sent to a website. You can view the IP address that is sent to websites by going here:

The problem you are having is likely from the cache files stored on your computer for the website. Try clearing the cache for whichever browser you are using. Note that this will also delete previously saved passwords used for access, but that may be your problem.

To the OP: That address is unique within your local network – but it is far from globally unique.


When your Mac gets an Internet address like 192.168.0.1, that is in one of the special private ranges that is never routed over the public Internet. There might be 100 million other people who all have the address 192.168.0.1 for their computer, and who all have 256 IP addresses (192.168.0.0 – 192.168.0.255) available for their local use.


Your router plays a clever game with remapping IPv4 addresses and port numbers to make things all work, so no matter how much of that 192.168.0.* range you are using, you're only taking up one of the more valuable globally-unique IPv4 addresses.
