I wrote a tiny DNS filtering daemon that does exactly the same - https://github.com/apankrat/dnswhisperer https://github.com/apankrat/dnswhisperer I've been using it routinely for past couple of months and it works really well. It blocks web ads, but it's blocks in-app ads and tracking as well. Tailing a log when launching an iPad game make for an interesting read. If anything slips through, just check the log, add the offender to the blacklist and restart the daemon.
