I have a personal domain name. I got it because my first name was available with my country tld.

I use it for email, which I will most likely keep forever, but how about my self-hosted stuff?

I use Slack's Nebula to access my self-hosted resources externally.

Would you mind exposing your VPS:es IP:s to the world by adding them as subdomains? In my case lighthouse1.myname.tld and lighthouse2.myname.tld?

I feel much more secure using DuckDNS for those IP:s as it should make it much harder to identify my attack surface.

Does it make sense or am I just paranoid?

I really don't like the idea of my attack surface being easily identifiable just by my email or first name.
