Following the discussions in the list, I made a test on one of our
servers, which is in an ISP's datacenter.
The result is below:
$ dig +short rs.dns-oarc.net txt
"188.8.131.52 DNS reply size limit is at least 490"
"184.108.40.206 lacks EDNS, defaults to 512"
"Tested at 2010-05-04 02:23:51 UTC"
Does this mean our ISP's filrewall block EDNS query/response?
