That chapter doesn't show any PTR records, for the reverse zones of any *public* address range, pointing back to a "localhost" name. It only shows a PTR record in the reverse zone for the 127.0.0/24 private range, which is what enables a reverse lookup for 127.0.0.1. Your ISP isn't (or shouldn't be) hosting reverse zones for any range under the 127/8 private block, on your behalf. That's your responsibility; hence the term "private". And, as Tony mentioned, these days it's highly questionable whether "localhost" entries in *any* zone, forward or reverse, serve any useful purpose, and may actually cause harm. - Kevin On Mon, Jun 21, 2021 at 12:48 PM <techli...@phpcoderusa.com> wrote: > Hi, > > This book : > https://www.oreilly.com/library/view/dns-and-bind/0596100574/ch04.html > says I should manage the localhost within my zone (SOA) and reverse > lookup / PTR. > > I do not manage my revers lookup / PTR the IP owner does that. > > Any thoughts on managing the localhost within the zone file and PTR? > > Thanks!! > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to > unsubscribe from this list > > ISC funds the development of this software with paid support > subscriptions.
