Not sure exactly what you want, but like this may be what you want. https://github.com/PeterDaveHello/ipinfo.tw
There are simpler solutions that are just a php script on your web server if you’re only interested in IP address (I couldn’t find a good example quickly on mobile)
I think that the answer to this depends on the audience and the topic or nature of the discussion.
I prefer precise, technical language if the audience has experience in the topic. You can save a lot of time by not explaining things that the readers should, reasonably know.
I think simpler language is appropriate for a more general audience or higher level discussion.
It can be challenging to find the right balance on a forum, like this, where you don’t necessarily know who the audience is.
