ISC DHCP 4.3.0 is Live!

ISC DHCP 4.3.0 is now online!

As mentioned in the previous blog by Shawn Routhier, the theme behind the of DHCP 4.3.0 is “v6 uplift”. Certain features that were specifically designed for DHCPv4 is now available for DHCPv6, making network management of IPv6 network more manageable and simple. As Shawn stated “[we] tried use the same commands or similar commands so that moving from a DHCPv4 feature to DHCPv6 is as painless as possible.”

    When i run dhclient for ipv6 i am getting the following error,

    no link-local IPv6 address for eth0

    When i manualy enabled ipv6 in the interface, then its working fine. Is there any fix for this issue?

    Thank you for your comment. This is expected behavior. You must have IPv6 enabled on an interface before it can use DHCPv6. A test for IPv6 link-layer addresses is the way dhclient(8) can tell if IPv6 is enabled. (See option “-D” in the dhclient manual.)

    On this particular question, on how to enable IPv6 for your interface, you might want to follow up with a support forum for your OS (or distribution.) If you have further questions about the use of ISC DHCP, please join and participate at our DHCP-users mailing list:
