Hello, In line with ISC's deprecation policy, I am notifying the mailing list of our intent to deprecate the "sortlist" options and a value "fixed" for "rrset-order" option.
These options allow to specify a on order of the resource records in the responses. The "fixed" value for "rrset-order" option will make named to record the order the records are defined in the zone file and it's disabled at the compile time because it blows up memory use. Relying on the order of the resource records in the DNS responses has been always wrong, but we are still keeping the "rrset-order" option, but please don't use it. The "sortlist" option allows to define a complicated rules when and how to reorder the resource records in the responses. The same caveats as with the "rrset-order" apply - relying on any specific order of resource records in the DNS responses is wrong. We are not aware of any other (major) DNS server that would have similar behaviour as this was never specified in the DNS protocol. If you know of any software or hardware relying on any specific order of the resource records in the DNS messages, it needs to be reported as a bug to the respective vendor. They will be deprecated as of BIND 9.20 and removed in BIND 9.22. Cheers, -- Ondřej Surý (He/Him) ond...@isc.org My working hours and your working hours may be different.
