> when i do want filtering i use opendns, because their anycast was built some years ago and it's extremely stable and mature. i expect quad9 to get there eventually, but i don't expect to ever need to use them, because i have three alternatives at higher priority: running my own; using a raw unfiltered service such as google; or using an older and very mature service like opendns.

Hi Paul, 

I think you meant to reply to Ken, I only did a test after seeing his
post, and since AU is next to Asia..... 

I also run my own DNS's and dont use other, I also have many pull-ins of
nasty domains who ought be NXDOMAIN'd so dont need the services of those
types of public DNS resolvers :) 

Kind Regards, 

Noel Butler
