<div dir="ltr">Um, I really don't think you can make a blanket statement like that with regards to DNS. Sure some DNS topics are off topic - eg "how do i configure my BIND" but others are on topic such as "this domain / series of domains are not resolving correctly for xxx isp/everyone, please confirm / pass on message to yyy to investigate/resolve"<div>
