IPv6

Additionally to IPv4, D-Series telephones support the use of IPv6 in a dual stack setup together with IPv4 or as IPv6 only. Shipped phones are configured with IPv6 disabled.

Additionally to being 'disabled', IPv6 supports the following modes:

  1. DHCP
  2. SLAAC

In DHCP mode, IPv6 address(es), routers, DNS servers and such things as provisioning information are retrieved from a local DHCPv6 server. SLAAC mode uses router advertisements send out by a software called 'router advertisement daemon' (e.g. for linux os: radvd) to configure the phone's network.

A 'manual' mode ist intentionally missing. Though it is possible to assign global IPv6 addresses to devices manually, it is highly unusual to do this. Therefore a router advertisement service needs to be present and configured correctly for IPv6 to work on D-Series telephones.
