You're right but for the wrong reason. You are referencing the private blocks that are designed for private use. The vast majority are not designed for private use.

The reason it's not unique (using my rudamentry understanding of networking) is because multiple routers can broadcast the same IP so devices can use the closest router.

However I think it's fair to say IP address are intended to be unique to an org while private ips are not.

Sure, but the person I'm replying to wasn't making a distinction here. They're just saying, "Have you ever changed the static IP address of a computer", where does that exclude RFC1918 IP addresses? I'm right for the right reasons IRT to the person I'm replying to. There are IP addresses which are absolutely not globally unique in any way, shape, or form by design.

> I think it's fair to say [public] IP address are intended to be unique to an org while private ips are not.

"Unique to an org", that's massively different from "globally unique" which is what the person I replied to suggested.

> multiple routers can broadcast the same IP so devices can use the closest router.

100% correct here, that's the biggest reason why you'd have an IP address shared among a lot of different devices.

Real talk.

I’ve been working in tech for 20 years, am coming off a year-long sabbatical, and for the past couple of months have been struggling with the feeling that the joy is gone and I should consider a radical career change.

Reading (what feels to me as) the aggressive pedantry of parent commenter in this thread is giving me a straight up anxiety attack. I’m not sure I have it in me anymore to be in meetings with people whose brains work this way.

Is it like this in every industry or is it more concentrated in tech? I don’t know who’s going to see this, but if you have any perspective or feedback you’d like to share, I’m all ears.

If someone says, "Tom Hanks played Jon Snow in Game of Thrones", and then you reply "that's incorrect, it was Kit Harrington", and then people say "well it's really Tom Hank's cousin that played him", which is still incorrect, is it aggressive pedantry to point out that's still wrong?

IP addresses are not globally unique. IP:PORT is not globally unique. Kit Harrington played Jon Snow in the HBO series Game of Thrones. These are just cold, hard, facts.

Looking for real feedback here, as I don't really want to give anyone panic attacks, but what would you suggest I say to posts attempting to correct me saying I'm wrong when I know they're factually incorrect? Just accept the falsehoods?

This is the new world we live in, the large group finds 'social correctness' more important than actual correctness.

If you find a good answer to this please let me know.

I've read books on this topic, and they say to come at the problem from an empathetic view point asking questions and trying to understand the person, however I suggest that you simply dont waste your time, you can't fix peoples broken understanding.

I've had hyper-pedantic arguments in many workplaces, but they're usually focused in tech or other "intellect driven" fields.

A lot of people (Americans especially, I guess due to their Silicon Valley) think you need to work in tech to work in tech. There are tech jobs in every industry, both IT and other types of tech. I recommend not being in the tech industry - working for a manufacturer with embedded systems or doing IT for a finance company is a lot better for your mental health.
