What Happens Next
=================
Bug reports submitted to us in this manner are handled based on
perceived severity in relation to other bugs. We handle reports as
time permits so there is no guaranteed response time for these
reports.
If you feel the issue you are reporting is a security issue, please
see http://www.isc.org/security/reporting-issues for details on how
to report it, including the PGP key you may use.
If it is of a non-security yet still urgent matter, you may reply
to this message to add further information.
Public Visibility of Bugs
=========================
Most bind and dhcp bug reports submitted since July 7, 2017 are visible
to the public at https://bugs.isc.org <https://bugs.isc.org/> after
review by the developers.
If you want this report to be withheld from public view, please
reply to this message with your request.
All reports submitted to
bind9-confidential@isc.org <mailto:bind9-confidential@isc.org > and

Other Support Options
=====================
If your organization requires more immediate attention, ISC offers
paid support options. Please see http://www.isc.org/services/support
for more information.
If paid support is not an option, please consider making a donation
to ISC. We don't require a donation -- we will work on your report
just as quickly whether or not you can donate -- but we always need
and welcome community support. See http://www.isc.org/donate/
Run a Supported Version
=======================
If you are not running a supported version of our software, please
upgrade. Bug reports against unsupported versions of BIND are
discouraged, as your issue may have already been addressed.
You can find the latest versions of our software here:

Two items:
----
#1
It would be useful to see support for RFC 6939 added to dhcrelay for DHCPv6.
Specifically, the insertion of OPTION_CLIENT_LINKLAYER_ADDR (79) , which
provides the client MAC to dhcpd as a relay option.
----
# 2
It would be useful to see support for providing external programs
information on DHCPv6-PD prefix assignments so that systems used as routers
could then take action to add routes for delegated prefixes.
This could be as simple as (1) creating a log event with the needed
information (prefix, expiry, and next-hop) that could be streamed to a
specific file; or (2) adding support to call an external script with the
information past as a list of as arguments; or (3) maintaining a
prefix-delegation database that keeps track of active prefixes delegated.
My personal preference would be the second option to call an external
script.
----
These two items are important for enabling IPv6 with DHCPv6 for open source
network routers and firewall projects, such as VyOS.
They also compliment functionality already in DHCPd, and would provide a
way to leverage these features without the use of proprietary relay agents.
I know that dhcrelay is not seen as a high priority for the project, but I
hope I can convey how important this functionality is for both IPv6
adoption as well as open source router and firewall adoption.
