IPv4 and IPv6 Wired Network Settings
You can configure the devices to operate in IPv4, IPv6, or dual-stack (IPv4/IPv6) mode.
After establishing wired network connectivity, the devices obtain the IPv4 or IPv6 network settings from a Dynamic
Host Configuration Protocol (DHCPv4 or DHCPv6) server. We recommend using DHCP where possible to elim-
inate repetitive manual data entry.
You can also configure IPv4 or IPv6 network settings manually.
Note: Yealink devices comply with the DHCPv4 specifications documented in RFC 2131, and DHCPv6 specifications doc-
umented in RFC 3315.
