if I have communications with someone through the internet with a homeserver. I would inevitably give out my IP address. Is that a bad thing? In my country they don’t have services like that, RTCing would be a bit sluggish using available euro servers.
That’s just not true. It is, some might say, ridiculously hard to do because these days there are so many i’s to dot and t’s to cross, but it’s not impossible. A friend hosts his domains’ email at home.
For that, that person must have paid the static IP address.
