I have a question on the DHCP Client FQDN Option for registering DDNS
records. We have a commercial DHCP server which is configured to register
the client's A record with the FQDN listed in the Domain field of Option 81
in the DHCP Request packet. This registration works correctly.

However, the DHCP server is registering the client's PTR record with the
clients hostname, but a different DNS domain - i.e. not the FQDN listed in
the Domain field of Option 81 in the DHCP Request packet. This creates a
situation where the client has a different FQDN listed in the PTR record and
the A record.

I assume that this is not expected behaviour, but "The DHCP Client FQDN
Option"
(http://www.ietf.org/internet-drafts/draft-ietf-dhc-fqdn-option-05.txt
<http://www.ietf.org/internet-drafts/draft-ietf-dhc-fqdn-option-05.txt> )
does not explicitly state that the PTR registration SHOULD / MUST / MAY use
the FQDN that the client responds with.

Regards,

Adrian Keasey
