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.
You need two static email addresses?
Edit: At this point I’ll have another service provider to have my own email.
In DNS you have a direct zone for records A, AAAA, MX, TXT, etc and an inverse zone also called rDNS for PTR records.
