Edit report at https://bugs.php.net/bug.php?id=75909&edit=1 ID: 75909 Updated by: mattficken@php.net Reported by: philip at kerzap dot com Summary: dns_get_record does not support CAA record type on Windows -Status: Open +Status: Wont fix Type: Bug Package: Network related Operating System: Windows PHP Version: 7.2.2 Block user comment: N Private report: N New Comment: Windows DNS impl doesn't support CAA record type. This is a behavior difference and is a won't fix Previous Comments: ------------------------------------------------------------------------ [2018-02-13 04:05:26] mattficken@php.net Windows doesn't seem to support CAA at all, surprisingly. For example, nslookup: C:\php-sdk>nslookup Default Server: google-public-dns-a.google.com Address: 8.8.8.8 > set q=CAA unknown query type: CAA > set q=TXT > Also, see: https://social.technet.microsoft.com/Forums/en-US/2399c372-89ad-4254-a7a9-7ab55af7a486/do-any-versions-of-dns-server-support-certification-authority-authorization-records?forum=winserveripamdhcpdns Therefore, PHP could only do it with a userland DNS library. Should be a Wont fix :( Thanks for pointing this out though :) ------------------------------------------------------------------------ [2018-02-12 12:02:21] ab@php.net Thanks for reporting. The current Windows API doesn't seem to provide a way to query these record types. One can query an authority of a host, but not the autority record itself. Until I've overseen something, there's no way to map this functionality currently :( Thanks. ------------------------------------------------------------------------ [2018-02-02 22:07:20] philip at kerzap dot com Description: ------------ Support for this record was added to dns_get_record in 7.0.16, but Windows uses a separate implementation of dns_get_record (defined in dns_win32.c) that did not get updated. The DNS_CAA constant is defined on Windows.
