NetworkManager's Systemd DHCP Code Now Supports DHCPv6

The latest feature addition ahead of the upcoming release of NetworkManager 1.2 is proper DHCPv6 support for IPv6 users.

Ths commit to NetworkManager Git explains, "Until now the internal DHCP client could start a DHCPv6 transaction but was not able to parse the lease and pass the information back to the core. Add the missing glue code to make this work."

The work is in relation to this bug report. "The internal DHCP client doesn't support DHCPv6 at the moment, but probably we only need to add some code to handle the lease from libnetworkd."
