Visited a client site and ran various ‘my ip address’ site to determine what is the External IP address the provider assigned. Noticed that each device resulted a different value. For example their phone and their tablet gave different values where that last segment changed (xxx.xxx.xxx.19 and xxx.xxx.xxx.20), yet when we ran myipaddress in our device gave a whole different value in all segments.
We understand that the internet provider assign the cable modem or location a single dynamic external ip. The location router managed a total different internal ip sequence values and assigns it to each device connecting to the wifi or router within the location. Thus the cable modem has 1 IP address and the devices within the location has different ip address.
Why would the “my IP address” website display different IP address in all devices connected to the same wifi?
