For the end-user public/internal IP doesn't have any disadvantages. Some say it's safer. That's BS. proper setup firewall it doesn't matter anything if you have internal or public IP.

btw private IP doesn't exist, unless you own the IP, which you can't. You can purchase the IP from services that "own" the IP only for a limited time. IP's are like ground in Malaysia. You can buy it for a specific amount of time, but you can't own it. Nor do these services actually "own" it.. They are just appointed proper delegation.. internet is tricky but basically no one "owns" anything.. it's regulated and maintained by companies that "sell" their "services and regulation" to you, ISP, web-host and other companies but no one really "owns" anything.

So just as much as "private" land doesn't exist in Malaysia things like "private IP" don't exist either.

It's public IP or internal IP of the internal network with a shared public IP.

Neither case it's private. Best case it's rented and giving to you the authority to decide what to do with it, but it's never truly "owned"
and thus never truly "private"

Yes some might argue:" sure you have private land in Malaysia" that's topic of interpretation. You basically bought the rights for the land
to manage it for 99 years. Included in this "managing rights" is your right to decide who might enter or not. So you might argue that's "private"
but since you don't "own" it, but only "rented" it, it's not really yours anyway and thus as such it's not really "private" because the government
can always just change the plans and then you loose your ground to a "public" authority, which is the government, state, whatever.

Anyway, back to Networking, NAT doesn't make your network safer nor does NAT from your ISP make you safer nor is anything here private
either. Your hardware at home may be private. Your ISP hardware may be private. But no one can really "own" the IP or other protocols and their
associated variables like an IP address.

biggest security leak for 99,999% of the people is they are logging into their computers every day using an account with elevated/administrator rights.

Just visit the wrong website, open the wrong email, open the wrong USB stick and that's it, gone is your security and programs in the background without you knowing it are now executed with full rights to do whatever they want to do on your system.

So there's no negative thing from having a public IP.

The benefits are easy to spot: not hosting anything? No benefits!

Want to host any service for yourself? You can open a specific port for that service on your local router and it works.

With a shared public IP and internal IP behind it of course this hosting of services doesn't work.

That's the only real benefit.

Since the vast majority of the people have no clue how to host any service, they won't need it.

And those that want to host a service, even if it's just a game server for a private group of friends, just call your ISP and within 10 minutes you got it up and running.

Reboot your router though.
