dig terminal command in Linux turns up different IP address than using website ip detector ...thoughts?

Hi everyone, I have a basic question. I followed the guide on the following website https://www.cyberciti.biz/faq/how-to-find-my-public-ip-address-from-command-line-on-a-linux/

and used the dig +short myip.opendns.com @resolver1.opendns.com command. I was given an ip address 104.200.23.95 which seems to point to somewhere in Texas....

​

However when I use the IP detecting websites such as whatismyipaddress etc it returns me with another number, 94.x.x.x. which points to a seemingly valid location since the geolocation information displayed is accurate

can anyone tell me why I am getting 2 separate results, from a technical standpoint? I am just trying to understand this. ultimately my end goal is to create a proxy server on my computer so I can tunnel my traffic while I am traveling.

​

thank you!
