(By-the-way, why is EDNS/RFC 2671 not advancing on the standards
track?)
Good question.
Rgds,
-drc
It's on the dnsext charter though a little late.
Jun 2005 RFC2671 (EDNS0) to Draft Standard
Most of the issues with RFC2671 are the result on non
conformance w/ RFC 103[45] and firewall that *think* they
know what is a valid DNS packet or feel that IP fragmentation
should not be allowed.
Note the later two usually affect the client side and when
lookups start failing they usually address the issue.
The non conformance with RFC 103[45] usually takes the form
of dropping packets the server doesn't know how to handle
rather than returning a error code.
Note: in general EDNS0 just works.
