Ive been using pi-hole for a few years now, and i really like it - actually so much, that i want to let other people use it
Im considering hosting an pi-hole server for some family members / friends, and allowing UDP/TCP 53 to be open on my public IP.
But im concerned about the security regarding hosting an small "private" DNS server.
A few years back i read that you could amplify and DDoS attack using public DNS servers.
So is it safe to open up for DNS requests, from the internet to my pihole?
OBS - The friends and family are using dynamic IPs, and its therefor not an option, to limit the source.
