Hello Mritunjay: You'll be pleased to know that we are addressing this issue in our upcoming maintenance releases, 4.3.6 and 4.1-ESV-R15 due out July '17, and our feature release of 4.4.0 (release date is TBD). For the maintenance releases, the new behavior must be enabled at compile time by a new flag in includes/site.h, ENFORCE_DHCPV6_CLIENT_REQUIRE. Beginning with 4.4.0, the behavior will be included by default. This is mitigate any disruption users might see with the maintenance releases. We like to recognize our contributors by citing them in our release notes. If you would like to be so noted, please respond with how you would like to be identified. Most often it is by name and organization. I'd like to thank you for taking the time and interest to report this issue to us and encourage you to continue submitting feedback in the future. Regards, Thomas Markwalder ISC Software Engineering
