Do you have any recommendations for recursive DNS servers for a medium sized (20-30k users) ISP. We have used powerdns and unbound but sometimes find the caching times a bit on upper side. Any suggestions between these two or anything new? Also need points on how much we tune the settings pros and cons if any.
The university I worked at ran ISC BIND9 on 2 machines as recursive resolver and authoritative server. You can run multiple of them and assign them randomly to your customers if the load is too high. -- Gruß Marco Send unsolicited bulk mail to 1754606680muell@cartoonies.org
