I have been using this since August 2019 without issues. #cache-min-ttl: 900 # https://blog.apnic.net/2019/11/12/stop-using-ridiculously-low-dns-ttls/ # dares setting the minimum cache to something between 40 minute and 60, # so how about 50 minutes? However it predates RFC 8767. #cache-min-ttl: 3000 # Why not just make it hour directly, while that is considered as a # maximum reasonableish value? #cache-min-ttl: 3600 # vim: filetype=unbound.conf
