Hi all, I've just tested the PowerDNS Recursor 3.2 with its out of the box configuration against the tests outlined at https://www.dns-oarc.net/oarc/services/replysizetest
It seems that EDNS is disabled by default, which is confirmed by the comment attached to changeset #1430 (http://wiki.powerdns.com/trac/changeset/1430) Looking at the source it seems in 3.2 an option "disable-edns=no" was added which turns EDNS support on. A cursory test here shows that adding this to the stock config does cause the dns-oarc reply size test to report a reply size of 1200 vs 512 when EDNS is off. What is the status of EDNS support? Is it safe to rely on in production environments? What specifically does the "nothing but trouble" comment on the changeset refer to? Also, the buffer size of "1200" appears to be hard coded. Is there any particular reason for this value? I'm guessing it has to do with avoiding fragmentation, but it'd be nice to know for sure.
