I have been running a public DNS server for private purpose (never liked my ISP’s DNS servers, and the root servers were usually located too far away (at least those with easy to remember IPs).

Anyway, been testing it since this summer, and so far it’s been working great.

the DNS server running on a Debian virtual machine, hosted by Rootspirit, near Amsterdam.

IP address: 85.12.6.171

Hostname: vm1.rootspirit.com

Might not be an easy to remember IP address (unlike 4.2.2.1), but as I use that IP pretty much every day, it’s okay for me. ;)
