I s= uspect that somewhere along the line that a code writer will interpret that = to mean a random number generator is needed. Other than being potentially confusing nomenclature, answering at "random" = is essentially how a cache answers type=3Dany queries today. Come to think of it, deciding which set is the smallest (on the wire) might= be more tie consuming than just answering with the whole set - depending on= what bottleneck you fear most that might be a consideration. And predictiv= e might also take too much thinkin'. Caution: old fart's meandering text follows: While I long prefer an explicit notice that the ANY query is being "shut do= wn" answering with one (honest) set is no worse than being dumb enough to re= ly on asking a cache for "ANY". If anyone is asking an authoritative for "A= NY" at a name, they either can figure out they didn't get an "whole answer" = (and then trawl through the expected type codes) or, well, just go trawling = to start with. I have in mind a use case where I ask a zone apex for ANY. I should see a = SOA, NS set, etc. If not I obviously have a partial answer and then go traw= l for the types I expect to see at an apex. The code doing this has been te= sted and works, even identifying when one operator turned off ANY and then s= tarted it back up a month later. --B_3563190002_420550861 Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" MIIH2QYJKoZIhvcNAQcCoIIHyjCCB8YCAQExCzAJBgUrDgMCGgUAMAsGCSqGSIb3DQEHAaCC BaIwggWeMIIEhqADAgECAhAE64fxtFjS2DdV8JfouoFSMA0GCSqGSIb3DQEBCwUAMGUxCzAJ BgNVBAYTAlVTMRUwEwYDVQQKEwxEaWdpQ2VydCBJbmMxGTAXBgNVBAsTEHd3dy5kaWdpY2Vy dC5jb20xJDAiBgNVBAMTG0RpZ2lDZXJ0IFNIQTIgQXNzdXJlZCBJRCBDQTAeFw0xNjA4MDkw MDAwMDBaFw0xOTA4MDkxMjAwMDBaMIG9MQswCQYDVQQGEwJVUzETMBEGA1UECBMKQ2FsaWZv cm5pYTEUMBIGA1UEBxMLTG9zIEFuZ2VsZXMxPDA6BgNVBAoTM0ludGVybmV0IENvcnBvcmF0 aW9uIGZvciBBc3NpZ25lZCBOYW1lcyBhbmQgTnVtYmVyczEeMBwGA1UEAxMVRWR3YXJkIExl d2lzIDkgQXVnIDE2MSUwIwYJKoZIhvcNAQkBFhZlZHdhcmQubGV3aXNAaWNhbm4ub3JnMIIB IjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxGXAQjOhBCDPz1+sGOERDMvSCFWbOUws GUrXAHLGeEAGYTCpni8f7kYPH7RMalvbep2aVtkMSUn6HR1uY84b437ZZuHCviUn7Aw6itGE wrDyq7Pb7zTlqE/1kLVhKYrHA4sjhsQRHhBHevxWbb3SYU2IMNxJd4QFgRJIp4zDmAR7bzbH 1ZazFGfo/op0QRsfcpFYmBotbj/4SnldtFwZasr7zTK9wJRSXa9sspLXtQhBe9itxTHJRg0H BH66VcPX7iRra9XFzkM5JLXOT2nBDIxeqDsLKoTkRWiNoSWoDZylAqS3BfBppwq7eremR7zD LIaPN4Tbb8TCpORMCZuvswIDAQABo4IB7zCCAeswHwYDVR0jBBgwFoAU5wIjgABP2Ne8lAvZ P3Q5STI8inkwHQYDVR0OBBYEFBiOkLRCGoHjShiTxeM3n94XHm+2MAwGA1UdEwEB/wQCMAAw IQYDVR0RBBowGIEWZWR3YXJkLmxld2lzQGljYW5uLm9yZzAOBgNVHQ8BAf8EBAMCBaAwHQYD VR0lBBYwFAYIKwYBBQUHAwIGCCsGAQUFBwMEMEMGA1UdIAQ8MDowOAYKYIZIAYb9bAQBAjAq MCgGCCsGAQUFBwIBFhxodHRwczovL3d3dy5kaWdpY2VydC5jb20vQ1BTMIGIBgNVHR8EgYAw fjA9oDugOYY3aHR0cDovL2NybDMuZGlnaWNlcnQuY29tL0RpZ2lDZXJ0U0hBMkFzc3VyZWRJ RENBLWcyLmNybDA9oDugOYY3aHR0cDovL2NybDQuZGlnaWNlcnQuY29tL0RpZ2lDZXJ0U0hB MkFzc3VyZWRJRENBLWcyLmNybDB5BggrBgEFBQcBAQRtMGswJAYIKwYBBQUHMAGGGGh0dHA6 Ly9vY3NwLmRpZ2ljZXJ0LmNvbTBDBggrBgEFBQcwAoY3aHR0cDovL2NhY2VydHMuZGlnaWNl cnQuY29tL0RpZ2lDZXJ0U0hBMkFzc3VyZWRJRENBLmNydDANBgkqhkiG9w0BAQsFAAOCAQEA zhEJp9X6tm36lKKaxCdyjyETxL3oVPDmv2JHBD/T/xbqRH0vQfR34VkRnSO+5d8AqHGdhYTK 7yjB/vW52KjiQUiW9WnQFYdY5Q/Yv3cnVgi4zuuye9BPvyr87HbmJ0uafYjATnYziT71njO7 xKIQP6w0MFv8ugT/fXIZsV4NU2eGQEHhvPkR+WOt0KfFa5jEY1qXoj4iZmE21j+f0OhSTA9K EofM5chR6FCaOyomKPIYU1mcoQwcistCwfcdVhUCpmgazxn6fR89ZOOiKTXxhOHrILdO0pCI dlJ3xO6EBvFKBCOyRBkD2z7jcWm/U3GkkYBLyRMvH1Ki+q4vwKnFZjGCAf8wggH7AgEBMHkw ZTELMAkGA1UEBhMCVVMxFTATBgNVBAoTDERpZ2lDZXJ0IEluYzEZMBcGA1UECxMQd3d3LmRp Z2ljZXJ0LmNvbTEkMCIGA1UEAxMbRGlnaUNlcnQgU0hBMiBBc3N1cmVkIElEIENBAhAE64fx tFjS2DdV8JfouoFSMAkGBSsOAwIaBQCgXTAjBgkqhkiG9w0BCQQxFgQUU180Fm7AnPzqPgPX ZP/QuLfda2swGAYJKoZIhvcNAQkDMQsGCSqGSIb3DQEHATAcBgkqhkiG9w0BCQUxDxcNMTYx MTI4MjAwMDAyWjANBgkqhkiG9w0BAQEFAASCAQBZixcZ4CyanKzpffg/iDrM9hkoyuxosePk F+pKvgjdf0cubiy067CVVGo6mOrmjINS06XIVSqn1KF9qKR1yznKDT30hSE1eiSx5jpsIixH YaFKEnb7YBrAmtQaWVEFBMb165o1lmq+/v3vVlsQ3h5+ZUJsQRkshHYAB/Noxm4JJM3/q8vz Kk3yCSbL2BpeN88oXFt3hW1PJbdCS3k2KSf1TBa8Zn2TkdRWr/HeFHgfd1Bdrgfet2mI2Le2 3t+ICEUx12/tTMZCmnbIP7oIex138yObdAvPgF3ktU6RSYo6Z/u9uML3OJnCGtkmGtrUQqUD MDVTYNb+huCyfQheoKoB --B_3563190002_420550861--
