Good morning,
I have those Bind versions installed: BIND 9.10.1-x86 in a Windows Server 32 bit BIND 9.10.1-x64 in a Windows Server 64 bit Both versions have the SIT (Source Identity Token) EDNS option enabled by default. You have DiG 9.10-P1 (May 8 2014) and my problems start with 9.10.0-P2 (June 6 2014) Regards Staff IDS Da: Chiesa Stefano [mailto:stefano.chi...@wki.it] Inviato: mercoledì 22 ottobre 2014 14.44 A: IDS Submit; bind-us...@isc.org Oggetto: R: Again question about edns (like swupdl.adobe.com) Hello all.

DiG has thos options so that we could perform checks like these. Until Adobe fix their broken servers you can use a server clause to disable sending SIT requests to them. Obviously this does not scale. server <address> { request-sit no; }; Mark ------------------------------------------------------------------ But this doesnt solve the problem on others domains should be possible enable request-sit no for all domains and not manually add it? Because I think there are lot of domains with this problem L ------------------------------------------------------------------ \Server\Bind\bin\dig.exe @81.174.15.142 www.acer.it ; <<>> DiG 9.10.1 <<>> @81.174.15.142 www.acer.it ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 42228 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;www.acer.it.
