[idn] [q] cname, EDNS0



 dname?, DNSEXT ?

  i have two questions:

1.  i heard about dname but do not know what dname can do.
  - what's the difference between cname (i know cname) and dname.
  - also any reference about dname?

2.  i seem to have heard that the max. label length (63) can be
increased with EDNS0 (extended DNS?).
  - any reference about this feature?
  - if this feature can be explained briefly, would anybody
give an example, please?

thanks in advance.
