You do it exactly the same as any other zone. You create DNSKEYs. You sign the zone. You add DS records to the parent zone. -- Mark Andrews > On 18 Nov 2021, at 20:28, Divya wrote: > >  > Dear Admin, > > Has anybody implemented DNSSEC on IPv6 reverse zones? > Kindly help us to configure

And I can testify that this works. I have 2001:42a0::/32 signed via AFRINIC. One suggestion though. When one signs an IPv4 reverse - use NSEC - as everyone can guess what is there anyway. With IPv6 - you might want to use NSEC3 - as there can be huge holes in the reverse zone. Make the bad guy

Possible to condition a view based on the interface the query comes in on?

I wanted to provide enhanced recursive DNS to (internal) clients on an "opt in" basis, which is to say that clients could choose whether or not to receive enhanced replies based on what they configured as their local caching resolver. The enhanced services come in the form of a Response Policy Zone

Look in to "match-destination" in a view, i.e. acl abcd.anycast { 10.10.10.1; }; view "abcd" { match-clients { any; }; match-destinations { abcd.anycast; }; ... }; The response-policy definition (and associated zone) can

Thanks for the encouragement folks, I forged ahead and I've got a different error now: "response-policy zone 'rpz1.m3047.net' for view standard is not a master or slave zone" That's the final denoument. There are several intermediate steps, such as moving all zone definitions into the vie

DNSTAP overload condition logging

2021-11-18 Thread Carsten Strotmann
Hi, how can a BIND 9 operator detect an DNSTAP overload condition? My understanding is that BIND 9 worker threads write DNSTAP information into a circular buffer in memory, which is that read by a different thread to write out the data (to file or socket). Is there any indication to the user
