[pkg-dhcp-devel] Bug#731452: (no subject)

[Nicolas C.]

Hello,

This happens because ISC-DHCP does not follow RFC 4361 yet. The v4 
client sends an identifier (client-identifier), le v6 client sends a 
different identifier (DUID).

DDNS uses conflict detection to prevent a client with the same name to 
replace a record already there. This conflict detection is base on a 
signature of the identifier provided by the client.

Different identifiers => different signatures => conflict between v4 and 
v6 clients.

To make it work, v4 clients should send the same DUID as the v6 client :

http://www.ietf.org/rfc/rfc4361.txt

This should be fixed in ISC-DHCP 4.3 :
